Jeremiah 18:8

8 and if that nation, concerning which I have spoken, turns from its evil, I will repent of the evil that I intended to do to it.

Jeremiah 18:8 Meaning and Commentary

Jeremiah 18:8

If that nation against whom I have pronounced
Such a sentence as this, should immediately, upon the above declaration, do as Nineveh did: turn from their evil;
their evil of sin, their evil ways and works, as an evidence of the truth of their repentance for former sins: I will repent of the evil that one thought to do unto them;
as they change their course of life, God will change the dispensations of his providence towards them, and not bring upon them the evil of punishment he threatened them with; in which sense repentance can only be understood of God, he doing that which is similar to what men do when they repent of anything; they stop their proceedings, and change their outward conduct; so God proceeds not to do what he threatened to do, and changes his outward behaviour to men; he wills a change, and makes one in his methods of acting, but never changes his will.

Jeremiah 18:8 In-Context

6 "O house of Israel, can I not do with you as this potter has done? says the LORD. Behold, like the clay in the potter's hand, so are you in my hand, O house of Israel.
7 If at any time I declare concerning a nation or a kingdom, that I will pluck up and break down and destroy it,
8 and if that nation, concerning which I have spoken, turns from its evil, I will repent of the evil that I intended to do to it.
9 And if at any time I declare concerning a nation or a kingdom that I will build and plant it,
10 and if it does evil in my sight, not listening to my voice, then I will repent of the good which I had intended to do to it.
