Do they not provoke ... - literally, Is it not themselves ("that they provoke") to the shame of their faces?

Do they provoke me to anger? saith the Lord,.... No: he cannot be provoked to anger as men are; anger does not fall upon him as it does on men; there is no such affection in God as there is in men; his Spirit cannot be irritated and provoked in the manner that the spirits of men may be; and though sin, and particularly idolatry, is disagreeable to him, contrary to his nature, and repugnant to his will; yet the damage arising from it is more to men themselves than to him; and though he sometimes does things which are like to what are done by men when they are angry, yet in reality there is no such perturbation in God as there is in men:

do they not provoke themselves to the confusion of their own faces? the greatest hurt that is done is done to themselves; they are the sufferers in the end; they bring ruin and destruction upon themselves; and therefore have great reason to be angry with themselves, since what they do issues in their own shame and confusion. The Targum is,

"do they think that they provoke me? saith the Lord; is it not for evil to themselves, that they may be confounded in their works?''

But instead of vexing Him (Jahveh) they rather vex themselves, inasmuch as God causes the consequences of their idolatry to fall on their own head. אתם is used reflexively: se ipsos; cf. Ew. 314, c; Gesen. 124, 1, b. For the cause of the shame of their face, i.e., to prepare for themselves the shame of their face, to cover their face with shame; cf. Jeremiah 3:25. - For (Jeremiah 7:20) because of this idolatrous work, the wrath of the Lord will pour itself over the land in the consuming fire of war (cf. Jeremiah 4:4 with Jeremiah 5:17, Nahum 1:6, etc.), so as to cut off men and beasts, trees and fruit.

Do they provoke me to anger? saith the LORD: do they not provoke themselves to the confusion of their own faces?

19. Is it I that they provoke to anger? Is it not themselves? (De 32:16, 21; Job 35:6, 8; Pr 8:36).

7:17-20 The Jews took pride in showing zeal for their idols. Let us learn to be earnest in the service of our God, even from this bad example. Let us think it an honour to be employed in any work for God. Let us be as diligent ourselves, and as careful to teach our children the truths of God, as many are to teach the mysteries of iniquity. The direct tendency of this sin is malice against God, but it will hurt themselves. And they shall find there is no escaping. God's wrath is fire unquenchable.
