Jeremiah 18:8
If that nation, against whom I have pronounced, turn from their evil, I will repent of the evil that I thought to do unto them.
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.
