Hebrew & Septuagint length

In English translation the verse runs 24 words from the Hebrew and 25 from the Septuagint (LXX English) — closely comparable.

A rough comparison of the two English renderings, which tokenize alike — not a word-level alignment.

Word counts can differ between the Hebrew and the Greek without any difference in meaning — e.g. the Hebrew direct-object marker אֵת has no separate Greek word, and Greek often adds the article ὁ.

In the original languages it is 10 Hebrew tokens and 16 Greek tokens — but the two are counted differently (Hebrew bundles its prefixes and suffixes into one token; the Greek is in lemma form), so that isn’t a like-for-like length.

Trapp's Complete Commentary

John Trapp

Isa 44:18 They have not known nor understood: for he hath shut their eyes, that they cannot see; [and] their hearts, that they cannot understand.

Ver. 18. They have not known nor understood.] How should they, say, when infatuated and given up to an injudicious mind, or reprobate sense, as those? {Rom 1:28}

For he hath shut their eyes.] Heb., Daubed up their eyes from seeing, their hearts from understanding.

Joseph Benson's Commentary

Isa 44:18-20. They have not known, &c. — They want common discretion, and have not the understanding of a rational being in them. For what an absurdity is it for a man to dress his meat and make his god with the same piece of wood! Or to think that a log of timber hath any more divinity in it than it had before, because of the form man can give it, or any thing he can do to it! “When,” says Minutius Felix, “does it become a god! Behold, it is cast, fashioned, and carved! It is not yet a god. It is soldered, put together, and set up. Neither is it yet a god. Behold, it is adorned, consecrated, and prayed to! Then at length it is a god when men have chosen and dedicated it.” He hath shut their eyes — God hath. Not as if God made men wicked; he only permits them so to be, and orders and overrules their wickedness to his own glorious ends. And none considereth in his heart — By which the prophet implies, that the true cause of this, as well as of other absurd and brutish practices of sinners, is the neglect of serious and impartial consideration. He feedeth on ashes — An unprofitable and pernicious food, and no less unsatisfying and mischievous is the worship of idols. A deceived heart — A mind corrupted and deceived by deep prejudice, gross error, and especially by his own lusts; hath turned him aside — From the way of truth, from the knowledge and worship of the true God, unto this irrational and foolish idolatry; that he cannot deliver his soul — From this error, and the vengeance that will follow upon it; nor say, Is there not a lie, &c. — Is not this idol which I honour and trust to a mere fiction and delusion which will deceive me?

John Gill's Exposition

They have not known nor understood,.... Who the true God is, nor the worship that is due to him alone; they do not know nor understand divine and spiritual things; nay, they have not the knowledge and understanding of men; they want common sense that can do and say such things as before mentioned, both idol makers and idol worshippers:

for he hath shut their eyes that they cannot see, and their heart that they cannot understand; either the devil, as some think, the god of this world, that blinds their eyes from seeing the folly of such gross idolatry, which he, deceiving them, leads them into; or rather God himself, who, because they like not to retain him in their knowledge, gives them up to a reprobate and injudicious mind, to believe a lie, and worship a false god; this he permits, orders, and overrules to some good ends and purposes: this is to be understood of the eyes of the understanding, which, as the word (i) signifies, are "daubed" and plastered over, that there is no opening of them, and seeing with them; which is the judicial blindness and hardness of heart, which God sometimes in righteous judgment gives up men unto; see Rom 1:28.

Albert Barnes' Notes on the Bible

They have not known nor understood - They are stupid, ignorant, and blind. Nothing could more strikingly show their ignorance and stupidity than this idol worship.

He hath shut their eyes - God hath closed their eyes. Margin, ‘Daubed.’ The word used here, טה ṭah from טוה ṭûah denotes properly “to spread over”; to besmear; to plaster; as, e. g., a wall with mortar Lev 14:42; 1Ch 29:4; Eze 13:10; Eze 22:28. Here it means to cover over the eyes so as to prevent vision; and hence, metaphorically, to make them stupid, ignorant, dull. It is attributed to God in accordance with the common statement of the Scriptures, that he does what he permits to be done (see the notes at Isa 6:9-10). It does not mean that God had done it by any physical, or direct agency, but that it had occurred under the administration of his Providence. It is also true that the Hebrew writers sometimes employ an active verb when the signification is passive, and when the main idea is, that anything was in fact done. Here the main point is not the agent by which this was done, but the fact that their eyes were blinded - and perhaps all the force of the verb טה ṭah used here would be expressed if it was rendered in an impersonal, or in a passive form, ‘it is covered as to their eyes,’ that is, their eyes are shut, without suggesting that it was done by God. So the Septuagint renders it, Ἀπημαυρώθησαν Apēmaurōthēsan - ‘They are blind,’ or involved in darkness.

So the Chaldee, מטמטמן meṭmeṭemân (also in the plural) - ‘Their eyes are obscured’ or blind. It cannot be proved from this text that God is, by direct agency, the author by whom it was done. It was not uncommon to shut up, or seal up the eyes for various purposes in the East, and unquestionably the prophet alludes to some such custom. ‘It is one of the solemnities at a Jewish wedding at Aleppo, according to Dr. Russell, who mentions it as the most remarkable thing in their ceremonies at that time. It is done by fastening the eyelids together with a gum, and the bridegroom is the person, he says, if he remembered right, that opens the bride’s eyes at the appointed time. It is also used as a punishment in those countries. So Sir Thomas Roe’s chaplain, in his account of his voyages to East India, tells us of a son of the Great Mogul, whom he had seen, and with whom Sir Thomas had conversed, that had before that time been cast into prison by his father, where his eyes were sealed up, by something put before them, which might not be taken off for three years; after which time the seal was taken away, that he might with freedom enjoy the light, though not his liberty.’ (Harmer’s Obs. vol. iii., pp. 507, 508. Ed. Lond. 8vo, 1808.)

Matthew Poole's English Annotations

They have not known or understood: this showeth that they want common discretion, and have not the understanding of a man in them. He, to wit, God; who is easily understood, and is oft expressed by this pronoun he; and to whom this very act is frequently ascribed in other places of Scripture. And therefore men need not to be shy in ascribing it to God here. Which yet is to be soberly understood; not as if God did make men wicked, but only permits them so to be, and orders and overrules their wickedness to his own glorious ends. And such passages as these are added in such cases to give an account of the prodigious madness of sinners herein; because, as they wilfully shut their own eyes, and harden their own hearts, so God judicially blinds and hardens them, and sends strong delusions upon them, and gives them up to believe lies, and then it is no wonder if they fall into such dotages.

Whedon's Commentary on the Bible

Daniel D. Whedon

18-20. The whole system of idol religion, in like manner, is simply foolish. Its votaries embrace it only to be blinded in conscience and reason. The makers and worshippers of idols are alike fools. And the sarcastic prophet cannot lament the dementing effects of the idol system in language more fitting than in the exactly literal words of Isa_44:19-20, which sufficiently explain themselves.

The Pulpit Commentary

They have not known nor understood. The cause of all this folly is a Minding of the understanding, divinely caused in the way of punishment, on account of their having wilfully closed their eyes to the truth. Because they "did not like to retain God in their knowledge, God gave them up to a reprobate (or, undistinguishing) mind". (Rom_1:28; comp. Isa_29:10) He hath shut; or, One hath shut. But the reference is in either case to God. The word translated shut" means literally plastered" or "smeared."

Keil & Delitzsch

C. F. Keil & F. Delitzsch

So irrational is idolatry; but yet, through self-hardening, they have fallen under the judgment of hardness of heart (Isa 6:9-10; Isa 19:3; Isa 29:10), and have been given up to a reprobate mind (Rom 1:28). "They perceive not, and do not understand: for their eyes are smeared over, so that they do not see; their hearts, so that they do not understand. And men take it not to heart, no perception and no understanding, that men should say, The half of it I have burned in the fire, and also baked bread upon the coals thereof; roasted flesh, and eaten: and ought I to make the rest of it an abomination, to fall down before the produce of a tree?" Instead of טח, Lev 14:42, the third person is written טח (from tâchach, Ges. 72, Anm. 8) in a circumstantial sense: their eyes are, as it were, smeared over with plaster. The expression אל־לב השׁיב or על־לב (Isa 46:8), literally to carry back into the heart, which we find as well as על־לב שׂים, to take to heart (Isa 42:25), answers exactly to the idea of reflection, here with reference to the immense contrast between a piece of wood and the Divine Being. The second and third לא in Isa 44:19 introduce substantive clauses, just as verbal clauses are introduced by ואין. לאמר is used in the same manner as in Isa 9:8 : "perception and insight showing themselves in their saying." On būl, see Job 40:20; the meaning "block" cannot be established: the talmudic būl, a lump or piece, which Ewald adduces, is the Greek βῶλος.

J. A. Alexander on Isaiah

Joseph Addison Alexander

“They have not known, and they will not understand, for he hath smeared their eyes from seeing, their hearts from doing wisely.” The combination of the preterit and future makes the description more complete and comprehensive. As the smearing of the eyes is merely a figure for spiritual blindness, it is here extended to the heart, of which it is not literally predicable.

Ibn Ezra

Rabbi Abraham ibn Ezra

לא ידעו ולא יבינו They have not known nor understood. The seat of knowledge (רעת) is in those cavities of the brain that are nearer to the forehead; the understanding (בינה) is in the middle one, that is also in the middle of the head.

טח He hath shut. Comp. וטח and he shall plaister (Lev, 14:42); it is a transitive verb; the Lord is understood as the subject to it.

עיניהם Their eyes. The eye of each of them; this construction is not at all rare.

Isaiah, in the Prophets, opens this verse with 10 words (9 distinct Hebrew lemmas). Its most distinctive word is ṭûwach (“to overlay”). A historical commentator’s framing appears above. Read the whole chapter for the surrounding context.

Discussion questions

  1. What does “to overlay” (ṭûwach) contribute to the verse as a whole?
  2. Leviticus 14:42 shares the word «to overlay» with this verse. How do the two illuminate each other?
  3. “not” occurs 2× in this one verse. What is the effect of the repetition?
  4. These translations render this verse differently. What is at stake in choosing one wording over another?
  5. The verb «יָדְע֖וּ» is Qal Perfect. How does its form color the action?
  6. Reading how Trapp's Complete Commentary and Joseph Benson's Commentary read this verse, where do the two commentators agree and where do they part?
