Yirmeyah 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.

6 O Bais Yisroel, cannot I do with you as this yotzer? saith Hashem. Hinei, as the khomer (clay) is in the yotzer’s yad, so are ye in Mine yad, O Bais Yisroel.

7 At what instant I shall speak concerning a Goy (nation), and concerning a mamlachah (kingdom), to uproot, and to pull down, and to destroy it;

8 If that Goy, against whom I have pronounced, turn from their ra’ah, I will relent of the ra’ah that I planned to do unto them.

9 And at what instant I shall speak concerning a Goy, and concerning a mamlachah, to build and to plant it;

10 If it do ra’ah in My sight, that it obey not My voice, then I will relent of the tov, wherewith I said I would benefit them.
