Исаия 44:18

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.

God, by the prophet, goes on in this chapter, as before, I. To encourage his people with the assurance of great blessings he had in store for them at their return out of captivity, and those typical of much greater which the gospel church, his spiritual Israel, should partake of in the days of the Messiah; and hereby he proves himself to be God alone against all pretenders (Isa 44:1-8). II. To expose the sottishness and amazing folly of idol-makers and idol-worshippers (Isa 44:9-20). III. To ratify and confirm the assurances he had given to his people of those great blessings, and to raise their joyful and believing expectations of them (Isa 44:21-28).

44:18-19 Their minds are shut: Idol worshipers cannot see the irony in using one part of a log to warm themselves and another part of the same log to be their god.
