In his knowledge - Rather, "without knowledge; i. e., on comparing his powerless idols with the terrific grandeur of a tropical thunderstorm the man who can still worship them instead of the Creator is destitute of knowledge.

Every founder ... - Or, "every goldsmith is put to shame etc." He has exhausted his skill on what remains an image.

Every man is brutish - נבער nibar, is a boor, acts as a brute, who may suppose that a stock of a tree, formed like a man, may be an intellectual being; and therefore shuns the form as though it had life. See Isaiah 44:10, Isaiah 44:11. Of which verses, by the way, Dr. Blayney gives the following version to correct that of Bishop Lowth: -

Isaiah 44:10. Who hath formed a god? Or set up a graven image that profiteth not?

Isaiah 44:11. Behold, all that are connected with it shall be ashamed, And the artificers, they above all men! They shall assemble all of them; they shall stand forth; They shall fear; they shall be ashamed at the same time.

"That is, while they stand before the image they have set up, and worship it with a religious dread, the glaring absurdity of their conduct shall lead to their shame and disgrace."

With due deference to this learned man, I think this interpretation too refined.

Every man is brutish in his knowledge,.... Or science of making an idol, whether it be of wood, or of gold, or silver, or brass; he is no better than a brute, if he thinks, when he has made it, he has made a god: or, "because of knowledge" (w); for want of it; being without the knowledge of God and divine things, he is like the beasts that perish, Psalm 49:20,

every founder is confounded by the graven image; or put to shame on account of it; since, after all his art, and care, and trouble, in melting and refining, and casting it into a form, it is no more than a piece of gold, or silver, or brass, and has no deity, nor anything like it, in it:

for his molten image is falsehood; it is a lie, when it is said to be a god; and it deceives those who worship it, and place any confidence in it. Kimchi renders it, "his covering" (x). The covering of the idol with gold and silver, with blue and purple, as in Jeremiah 10:4, is all a piece of deceit, to impose upon the people, and lead them into idolatry:

and there is no breath in them; they are mere stocks and stones, lifeless and inanimate creatures; they have neither life themselves, nor can they give it to others.

(w) "propter scientiam", Pagninus, Montanus; "a scientia", Calvin, Grotius, Schmidt. (x) "tectio, sive obductio ejus", Vatablus.

In presence of such marvels of divine power and wisdom, all men seem brutish and ignorant (away from knowledge equals without knowledge), and all makers of idols are put to shame "because of the image" which they make for a god, and which is but a deception, has no breath of life. נסך, prop. drink-offering, libamen, cf. Jeremiah 7:15; here molten image equals מסּכה, as in Isaiah 41:29; Isaiah 48:5; Daniel 11:8. Vanity they are, these idols made by the goldsmith. A work of mockings, i.e., that is exposed to ridicule when the nullity of the things taken to be gods is clearly brought to light. Others: A work which makes mockery of its worshippers, befools and deludes them (Hitz., Ng.). In the time of their visitation, cf. Jeremiah 6:15.

Every man is {h} senseless in his knowledge: every goldsmith is confounded by the graven image: for his molten image is falsehood, and there is no breath in them.

(h) The more man thinks to do anything well by his own wisdom, and not as God instructs him, the more he proves himself to be a vile beast.

10:14 Every man - Every idolator.

brutish in his knowledge: or, more brutish than to know

14. in his knowledge-"is rendered brutish by his skill," namely, in idol-making (Jer 10:8, 9). Thus the parallel, "confounded by the graven image," corresponds (so Jer 51:17). Others not so well translate, "without knowledge," namely, of God (see Isa 42:17; 45:16; Ho 4:6).

10:1-16 The prophet shows the glory of Israel's God, and exposes the folly of idolaters. Charms and other attempts to obtain supernatural help, or to pry into futurity, are copied from the wicked customs of the heathen. Let us stand in awe, and not dare provoke God, by giving that glory to another which is due to him alone. He is ready to forgive, and save all who repent and believe in the name of his Son Jesus Christ. Faith learns these blessed truths from the word of God; but all knowledge not from that source, leads to doctrines of vanity.
