Verse 19. If thou - These are God's words to the prophet, rebuking his distrust in God, and promising him, that if he did return from his distrust in God's providence, he would restore him to the former favour he had with him, and he should be his prophet to reveal his mind to the people; and that if he would separate the precious truths of God from the vile conceits of men, then God would continue him as his prophet, to speak in his name to the people. But - He charges the prophet to keep his ground, and not to go over to wicked men.
Verse 21. The wicked - The wicked Jews. The terrible - And the power of the terrible Chaldeans.
