Jeremiah 18:8

If it do evil in my sight,.... What is sinful, contrary to the law and will of God, openly and publicly, in a bold and daring manner:

that it obey not my voice: in my word, and by my prophets, but…

I will repent of the evil ... I will repent of the good - All God’s dealings with mankind are here declared to be conditional. God changeth not, all depends upon man’s conduct.

The prophet is here sent to the potter's house (he knew where to find it), not to preach a sermon as before to the gates of Jerusalem, but to prepare a sermon, or rather to receive it ready prepared.…

I will repent speaking after the manner of men. The sense is, I will alter my treatment, for among men change of conduct implies change of purpose.
