Exodus 1 and Joshua 2 · Debate · Truthfulness

Is a Lie Ever Right?

The Hebrew midwives answered Pharaoh and Rahab turned away the king's men, and Christian teachers have disagreed on whether their words were sin.

A king's order to kill newborn sons set two midwives a question the church still argues.

Exodus 1:17 BSB
The midwives, however, feared God and did not do as the king of Egypt had instructed; they let the boys live.
The question
Is it ever right to deceive in order to save an innocent life?

Summary

The law and the apostles forbid false witness and lying among God's people, yet Scripture praises two answers given to protect the innocent. Samuel, sent by God to anoint a king while Saul still reigned, belongs to the same question. The church's teachers have weighed these cases in three ways, and each way has its holders across the centuries.

  • Augustine, Thomas Aquinas and John Calvin hold that every lie is a sin, even one told to save a life.
  • Hugo Grotius holds that a false word to one who has lost the right to the truth wrongs no one.
  • John Cassian, a monk of the fifth century, held that a lie may be the lesser of two evils.

The Texts Every Side Reads

Five passages, from the midwives in Egypt to the letters of Paul, carry the weight of the question.

Is a Lie Ever Right? takes the command to speak truth to its hardest case, where a true answer would hand an innocent person to a killer. It belongs to the value of truthfulness because every answer to that case says what truthfulness demands.

The question it answers is whether a false word spoken to save a life is still a sin. It gives the texts every side reads, the three answers and their holders, and the cases of the midwives, Samuel and Rahab. It then sets out the law of witness, the history of the question and the great books.

The midwives answered Pharaoh, “The Hebrew women are not like the Egyptian women, for they are vigorous and give birth before a midwife arrives.”
Exodus 1:19BSB

This is the answer the debate turns on, and its readers divide over whether it was false.

You shall not bear false witness against your neighbor.
Exodus 20:16BSB

The ninth commandment forbids false witness, and the positions differ over whether it forbids every false word or the false word that wrongs a neighbor.

But the woman had taken the two men and hidden them. So she said, “Yes, the men did come to me, but I did not know where they had come from. At dusk, when the gate was about to close, the men went out, and I do not know which way they went. Pursue them quickly, and you may catch them!”
Joshua 2:4 to 5BSB

Rahab's reply to the soldiers of Jericho is the second case that every reading must explain.

There are six things that the LORD hates, seven that are detestable to Him: haughty eyes, a lying tongue, hands that shed innocent blood,
Proverbs 6:16 to 17BSB

Both wrongs that the hard cases weigh against each other stand together in this list.

Therefore each of you must put off falsehood and speak truthfully to his neighbor, for we are all members of one another.
Ephesians 4:25BSB

The reading that lying is never right takes this command as a rule without exception.

Joshua 2:4 to 5, Proverbs 6:16 to 17, Ephesians 4:25

Three Answers to One Question

The never reading, the hearer's-right reading and the lesser-evil reading each answer three questions in their own way.

The three positions part over what a lie is, and so over the killer at the door and the midwives' reward.

The questionLying is never rightThe hearer's right to the truthThe lesser evil
What is a lie?Speech that signifies what is not in the speaker's mind, which is evil in its kind.A false word that violates the right of the one addressed to the truth.A false word, which is a wrong in itself and may still be the lesser of two wrongs.
May a person deceive a killer who asks where his victim is?No. The person may keep silent or keep the truth back, and must not speak what is false.Yes. The killer has lost the right to the truth, and the false word saves an innocent life.Yes, where no other way saves the life, since the life outweighs the wrong of the word.
What does Exodus 1:21 credit?Their fear of God and their mercy, while their false word was forgiven.Their fear of God, which moved them both to save the boys and to answer the king as they did.Their fear of God, by which they chose the higher duty of saving life.
A table of three rows, each with three answers.

Each Position Stated

Each position rests on its own account of what a lie is and of when, if ever, a false word may be spoken.

Lying is never rightAugustine, Thomas Aquinas, John Calvin

Augustine wrote On Lying in about 395 and came back to the subject many years later in Against Lying. There he held that God's kindness to the midwives and to Rahab was given for their mercy toward His people, and that their deceit earned none of it. He held too that the midwives would have done better to refuse both the lie and the killing, even if they died for it.

Thomas Aquinas gave the reason from the nature of speech. Words are natural signs of what is in the mind, so to signify by words what is not in the mind is a wrong in its kind, and every lie is a sin. He counted a lie told to help another a venial sin.

John Calvin, commenting on Exodus 1:19, held that the two women lied and that, since lying displeases God, they sinned. He held as well that God, in His fatherly indulgence, still valued their good work as if it were pure. He gave the ground in these words: "whatever is opposed to the nature of God is sinful; and on this ground all dissimulation, whether in word or deed, is condemned".

The hearer's right to the truthHugo Grotius

Hugo Grotius, in The Rights of War and Peace, defined a lie in the strict sense as a violation of the existing right of the person addressed. That right is the liberty of judgment that people owe one another when they speak, and it may be lost. Grotius allowed a false word where it is the only means of saving the life of an innocent person.

Grotius set this reading beside the false witness to or against a neighbor that Scripture so often forbids.

The lesser evilJohn Cassian

John Cassian, in his Conferences, Conference 17, likened a lie to hellebore, a poison that heals when a deadly disease threatens and kills when it is taken without need. He held that a lie may be used only under the pressure of a great danger, and he took Rahab as his example.

The site's tradition is Wesleyan-Pentecostal. John Wesley, from whom its Wesleyan stream comes, wrote on Joshua 2:4 that Rahab's answer was false and therefore sinful, though her intention was good. Scripture leaves this question open to more than one reading, and the site gives no verdict between the three positions.

The Midwives, Samuel and Rahab

Three cases set a ruler's power against an innocent life, and the positions read each one in their own way.

What God rewardedExodus 1:20 to 21
So God was good to the midwives, and the people multiplied and became even more numerous. And because the midwives feared God, He gave them families of their own.
Exodus 1:20 to 21BSB

The text names the cause of God's gift of families, and every reading of the reward begins from it.

Thomas Aquinas read these verses as the never reading does. He placed the reward of the midwives in their fear of God and their good will, and he held that the lie itself could merit nothing eternal. Augustine, in On Lying, held that the midwives are spoken of with approval for the promise of growth they showed. Mercy that saves a mortal life, he wrote, is a step toward loving the eternal saving of the soul.

Jamieson, Fausset & Brown and Albert Barnes read the houses God made as families and offspring, so that the midwives married and became mothers in Israel, and the Berean text renders the verse that way. John Calvin read the pronoun as masculine and held that God made houses for the Israelites through the piety of these women.

Did the midwives lie?Exodus 1:19

Rashi read the word the Berean renders vigorous as a word for midwives, so that the Hebrew women were as skilled as midwives themselves. The rabbis of the Talmud, in Sotah 11b, read it as a comparison to the beasts of the field, which give birth without help.

Adam Clarke held that the answer stated what experience shows. Women who labor in the open air through their pregnancy give birth quickly, he wrote, and Exodus 1:14 records the work of the Hebrews in the fields. The note of the Calvin Translation Society on Exodus 1:18 reports that John Lightfoot wrote of the midwives' words as no lie and as a confession of their faith.

John Calvin rejected the rabbis' account that the midwives had warned the women of the king's design and so came too late.

The heifer and the sacrifice1 Samuel 16:1 to 3
“How can I go?” Samuel asked. “Saul will hear of it and kill me!” The LORD answered, “Take a heifer with you and say, ‘I have come to sacrifice to the LORD.’
1 Samuel 16:2BSB

The LORD Himself tells Samuel what to say when Samuel fears that Saul will kill him, and every position must account for a concealment God commanded.

Adam Clarke, in his Commentary on the Bible, held that Samuel's word was strictly true, since Samuel did offer the sacrifice and could not have gathered the sons of Jesse without it. Gregory the Great, in his Commentary on 1 Kings, read the verse as a pattern for eluding tyrants by a pious deception, in such a way that the guilt of lying is avoided.

Rahab and the spiesHebrews 11:31 and James 2:25
By faith the prostitute Rahab, because she welcomed the spies in peace, did not perish with those who were disobedient.
Hebrews 11:31BSB

Hebrews names Rahab's welcome of the spies as the act of her faith, which is the act every position praises.

In the same way, was not even Rahab the prostitute justified by her actions when she welcomed the spies and sent them off on another route?
James 2:25BSB

James counts the escape she gave the spies among her deeds of faith, and the readings ask whether her words to the king's men belong among them.

John Calvin held that Rahab's falsehood was done for a good purpose and was not free from fault, and that God willed the spies to be delivered without approving the falsehood that saved them.

The Ninth Commandment and the Law of Witness

Barnes and Clarke differ over how far the ninth commandment reaches.

The Berean text of Deuteronomy 5:20 gives the ninth commandment in the same words as Exodus 20:16.

“You shall not spread a false report. Do not join the wicked by being a malicious witness. You shall not follow the crowd in wrongdoing. When you testify in a lawsuit, do not pervert justice by siding with the crowd.
Exodus 23:1 to 2BSB

The Book of the Covenant applies the commandment to the courts, where a false report or a crowd could pervert justice.

Albert Barnes read the four commands of Exodus 23:1 to 3 as illustrations of the ninth commandment, given mainly for evidence in legal causes. Adam Clarke read the commandment more widely, as forbidding slander, tale-bearing and every false statement that injures another in goods, person or character.

The Westminster Larger Catechism lists lying among the sins the ninth commandment forbids. It lists among them too the speaking of the truth unseasonably, or maliciously to a wrong end.

Stay far away from a false accusation. Do not kill the innocent or the just, for I will not acquit the guilty.
Exodus 23:7BSB

The law sets a false accusation beside the killing of the innocent and the just in a single command.

How the Question Came Down

The question has passed from the fathers to the medieval schools, the Reformers and the moderns.

The question has been argued in treatises, commentaries, catechisms and ethics from the fourth century to the twentieth.

What the Text Leaves Unsaid

Exodus 1 leaves three questions about the midwives without an answer.

The text neither praises nor blames the words the midwives spoke to the king. It does not say whether the midwives were Hebrews or Egyptians, and Albert Barnes, reading the Hebrew as midwives of the Hebrew women, held that their names are Egyptian. It does not say whether Pharaoh believed them, and it records only that he next commanded all his people to throw every Hebrew son into the Nile.

What Every Side Holds

Every position shares four teachings about God, the devil and the truth owed among God's people.

GOD CANNOT LIE

Every side confesses with the letter to the Hebrews that it is impossible for God to lie.

Hebrews 6:18

THE FIRST LIE

Every side reads the serpent's word to Eve in the garden as the first lie in Scripture.

Genesis 3:4

TRUTH AMONG GOD'S PEOPLE

Every side holds the law's command that God's people must not lie or deceive one another.

Leviticus 19:11

FAITHFUL DEALING

Every side reads that lying lips are detestable to the LORD and that those who deal faithfully are His delight.

Proverbs 12:22

Truth among God's people, Faithful dealing

How the Teachers Read It

Two teachers, of the second century and the eighteenth, speak to the source of lying and to the truthfulness of God.

died 202 · Irenaeus

Irenaeus, in Against Heresies, book 5, traces deceit back to the devil's first dealings with mankind.

1662 to 1714 · Matthew Henry

Matthew Henry, in his Commentary on the Whole Bible (1710), grounds the duty of truth in the character of God on Titus 1:2.

Read the page on Matthew Henry

“The faith and godliness of Christians lead to eternal life, and give hope and well-grounded expectation of it; for God, that cannot lie, hath promised it. It is the honour of God that he cannot lie or deceive: and this is the comfort of believers, whose treasure is laid up in his faithful promises.”

The Three Positions Weighed

Each position faces one objection that the other positions press hardest.

The never reading has the longest line of holders, from Augustine to Wesley.

A grid of the readings with their holders, traditions and works, one line each.
Cassian's objection1 paragraph

Against the never reading, John Cassian pressed the case of Rahab. Had she spoken the truth to the king's men, he held, she and all her house would have perished. She would not then have been joined to the people of God or counted among the forebears of Christ.

The objection to the hearer's right1 paragraph

The objection: Leviticus 19:11 gives its command to all Israel and makes no exception for a hearer who means harm.

Augustine's objection1 paragraph

Against the lesser-evil reading, Augustine answered Rahab's case by naming a third way. She could have told the king's men that she knew where the spies were and feared God too much to betray them. The spies she had hidden so carefully might still not have been found. Thomas Aquinas allowed the truth to be hidden prudently by keeping it back, and he held that a lie may not be told to deliver another from any danger whatever.

The New Self and the Truth

Paul's command to the new self stands where every position agrees.

Paul tells those who have put on the new self not to lie to one another, since that self is being renewed in the image of its Creator (Colossians 3:9 to 10).

Jesus answered, “I am the way and the truth and the life. No one comes to the Father except through Me.
John 14:6BSB
