The Words Emunah and Pistos

Emunah in Hebrew and pistos in Greek name faithfulness, said first of God and then of His servants.

A poet writing over a ruined city chose emunah for the great faithfulness of God.

Numbers 12:7 BSB
But this is not so with My servant Moses; he is faithful in all My house.

Summary

In the Hebrew Bible a form of the verb aman, neeman, calls God the faithful God and calls Moses faithful. The Psalms and the Prophets speak most of His emunah, His firmness toward His people. In Greek the adjective pistos means trustworthy, and it stands in Paul's letters, in Hebrews and in Revelation.

  • Emunah means firmness, and Scripture uses it for fidelity.
  • Pistos can mean trustworthy or, in a few places, believing, and the context decides.
  • Nehemiah 9:8 calls Abraham's heart faithful with the same form, neeman.

Faithful in All My House

The scene is the Tent of Meeting in the wilderness.

Emunah and pistos carry the Bible's teaching that God can be relied on and that His servants must be. They matter to every reader who has to decide whom to trust. The question they raise is what the two words mean and of whom Scripture says them.

Below stand the scene of Numbers 12, a table of four words with their counts, emunah of God in the Psalms and Prophets, and pistos in the New Testament. Then come a caution on each word, the teachers who read them and the lexicons a reader can open.

Miriam and Aaron spoke against Moses, and the LORD answered that He speaks with prophets in visions and dreams. Of Moses He said that he is faithful in all His house (Numbers 12:7). The Hebrew word is neeman, a form of the verb aman glossed faithful in the STEP word index.

Now Moses was faithful as a servant in all God’s house, testifying to what would be spoken later.
Hebrews 3:5BSB

Hebrews takes up the verse in Greek, where the word for faithful is pistos.

Four Words for Faithfulness

Each word's sense and count stand beside a verse where it occurs.

The Greek adjective pistos is used more often than the Hebrew noun emunah.

Emunah of God

The Psalms and the Prophets use emunah for the faithfulness of God to His people.

At Exodus 17:12 emunah names the steadiness of Moses' hands held up by Aaron and Hur. In the Psalms and the Prophets it becomes the word for God's own faithfulness, often joined to His loving devotion.

FAITHFULNESS TO THE CLOUDS

David measures God's emunah against the height of the sky, emunatekha, Your faithfulness.

Psalm 36:5

FAITHFULNESS TO ALL GENERATIONS

The psalmist proclaims God's emunah to all generations before he laments the fall of David's line.

Psalm 89:1

PLANS IN PERFECT FAITHFULNESS

Isaiah praises God for plans formed long ago and carried out in emunah.

Isaiah 25:1

BETROTHED IN FAITHFULNESS

Hosea's promise of a new betrothal uses be-emunah, in faithfulness.

Hosea 2:20

Plans in perfect faithfulness, Betrothed in faithfulness

Two Cautions

Each word carries more than one sense, and the verse decides which.

Strong's dictionary gives pistos two sides, "objectively, trustworthy; subjectively, trustful". In John 20:27 Jesus tells Thomas to stop being apistos and be pistos, which the STEP word index glosses unbelieving and believing, and the Berean text renders "Stop doubting and believe".

Adam Clarke read neeman in Numbers 12:7 as "a prefect or superintendent", a title of office, and he gathered other places where the word names a person set over others. The Berean text renders it faithful, and Hebrews 3:5 takes it in that sense.

Pistos in the New Testament

Six verses show where the adjective stands.

The words "God is faithful" stand in Paul's letters as a ground for comfort. In each case the word is pistos, and in each case it stands beside a promise, that God will keep His people, provide a way out of temptation or finish what He began.

  • God is faithful

    Paul assures the Corinthians that God, who called them into fellowship with His Son, is pistos.

    1 Corinthians 1:9

  • The One who calls you

    Near the end of his first letter to the Thessalonians Paul calls the God who called them pistos and promises that He will do it.

    1 Thessalonians 5:24

  • He who promised

    Hebrews grounds hope on the faithfulness of the One who promised, pistos.

    Hebrews 10:23

  • Faithful and just to forgive

    John joins pistos to just in the promise of forgiveness to those who confess.

    1 John 1:9

  • Faithful and True

    John's vision names the rider on the white horse Pistos, Faithful.

    Revelation 19:11

  • Faithful even unto death

    The risen Christ asks the church at Smyrna to be pistos to the end.

    Revelation 2:10

How the Words Have Been Read

Matthew Henry read pistos in John's promise of forgiveness.

1662 to 1714 · Matthew Henry

He Remains Faithful

Paul wrote these words to Timothy near the end of his life.

In 2 Timothy 2:13 the Greek sets apistoumen, we are faithless, beside pistos, faithful, in one short line.

if we are faithless, He remains faithful, for He cannot deny Himself.
2 Timothy 2:13BSB

The line closes a short saying of four conditions that Paul calls trustworthy.
