Commentary
12 notes on this verse(Verse 19 and following) And when they say to you, seek from the Pythons and the diviners, who make their enchantments, whether not the people seeks from their God for the living from the dead? To the law more and to the testimony. If they do not speak according to this word, it will not be morning light for them. And they will pass through it: they will fall down and be hungry: and when they are hungry, they will become angry and curse their king and their God.

When men tell you to consult
on Isaiah 8:19-20
When the people are urged to consult mediums "who whisper and mutter," the prophet asks why they would "consult the dead on behalf of the living" instead of their God. The test is "To the law and to the testimony," and whoever does not speak by this word has "no light of dawn," the sealed testimony of verse 16 as the measure for every voice.

To the law and to the testimony
Against the mediums of verse 19 Isaiah sets the written word. Barnes reads the call as a test of every voice by what God has revealed. Clarke ties the testimony to the witnessed writing of 8:1 to 4 and the law to the command of verses 11 to 15.
The record, by era

293. Second, the response is taught: should not the faithful people seek of their true God, for the living and the dead, that is, for the salvation of the living and the dead: is it because there was no God in Israel, that you send …
The Puritans and the Awakening3 voices
To the law - Let this dispute between you and them be determined by God's word, which is here and in many other places called the law, to signify their obligation to believe and obey it; and the testimony, because it is a witness between God and man, of God's will, and of man's duty. No light - This proceeds from the darkness of their minds, they are blind, and cannot see.
To the law, and to the testimony,....
Orders given to the prophet to write this prophecy, and publish it to be seen and read of all men, and to leave it upon record, that when the thing came to pass they might know that God had sent him; for that was one end of prophecy, John xiv.
The Nineteenth Century1 voice
To the law and to the testimony “Unto the command, and unto the testimony” - “Is not תעודה teudah here the attested prophecy, Isa 8:1-4? and perhaps תורה torah the command, Isa 8:11-15? for it means sometimes a particular, and even a human, command; see Pro 6:20, and Pro 7:1, Pro 7:2, where it is ordered to be hid, that is, secretly kept.” - Abp. Secker.

But the Hebrew rendered "because" is not this but "who"; and "if not," ought rather to be "shall they not"; or, truly they shall speak according to this word, who have no morning light (so the Hebrew, that is, prosperity after the night of sorrows) dawning on them [MAURER and G.

WHEN men will not learn of God, how huge their folly grows! If they despise the wisdom that is from above, how grievously does God allow them to prove their own ignorance! When a man will not bow down before God the Most High, immediately he buildeth for himself an idol; he maketh an image of wood or stone, and he degradeth himself by bowing before the work of his own hands.
WHEN men will not learn of God, how huge their folly grows! If they despise the wisdom that is from above, how grievously does God allow them to prove their own ignorance! When a man will not bow down before God the Most High, immediately he buildeth for himself an idol; he maketh an image of wood or stone, and he degradeth himself by bowing before the work of his own hands. When men will not receive the Scripture testimony concerning God’s creation, straightway they begin to form theories that are a thousand times more ridiculous than they have ever endeavoured to make the Bible account of it, for God leaveth them, if they will not accept his solution of the problem, to grope for another, and their own solution is so absurd, that all the world except themselves hath sense enough to laugh at it. And when men leave the Sacred Book of Revelation, ah! my friends, where do they go? We find that in Isaiah’s time they went to strange places; for he says in the 19th verse, that they sought unto familiar spirits, unto wizards that did peep and mutter; yea, they sought for things concerning the living, amongst the dead, and became the dupes of necromancers. It is marvellous that the men who most of all rail at faith are remarkable for credulity. One of the greatest unbelievers in the world, who has called himself a free-thinker from his birth, is to be found now tottering into his tomb, believing the veriest absurdity that a child might confute. Not caring to have God in their hearts, forsaking the living foundation, they have hewn out to themselves cisterns which are broken, and hold no water. Oh! that we may each of us be more wise, that we may not forsake the good old path, nor leave the way that God hath prepared for us.

To the law ... - To the revelation which God has given. This is a solemn call of the prophet to try everything by the revealed will of God; see Isa 8:16. If they speak not - If the necromancers - those that pretended to have contact with the dead. According to this word - According to what God has revealed. By this standard all their pretended revelations were to be tried. By this standard all doctrines are still to be tried. It is because - There has been a great variety of criticism upon this verse, but our translation expresses, probably, the true idea. The word rendered here ‘because,’ אשׁר 'ăsher, commonly denotes ‘which;’ but it seems here to be used in the sense of the Syriac? “Dolath,” or the Greek ὅτι hoti. No light - Margin, ‘Morning.’ Hebrew שׁחר shāchar. The word usually means the morning light; the mingled light and darkness of the aurora; daybreak. It is an emblem of advancing knowledge, and perhaps, also, of prosperity or happiness after calamity, as the break of day succeeds the dark night. The meaning here may be, ‘If their teachings do not accord with the law and the testimony, it is proof that they are totally ignorant, without even the twilight of true knowledge; that it is total darkness with them.’ Or it may mean, ‘If they do not speak according to this word, then no dawn will arise, that is, no prosperity will smile upon this people.’ - Gesenius. Lowth understands it of obscurity, darkness: ‘If they speak not according to this word, In which there is no obscurity.’ But there is no evidence that the word is ever used in this sense. Others suppose that the Arabic sense of the word is to be retained here, deception, or magic. ‘If they speak not according to this oracle, in which there is no deception.’ But the word is not used in this sense in the Hebrew.
