14 Thus says the Lord: "Against all My evil neighbors who touch the inheritance which I have caused My people Israel to inherit--behold, I will pluck them out of their land and pluck out the house of Judah from among them. 15 Then it shall be, after I have plucked them out, that I will return and have compassion on them and bring them back, everyone to his heritage and everyone to his land. 16 And it shall be, if they will learn carefully the ways of My people, to swear by My name, 'As the Lord lives,' as they taught My people to swear by Baal, then they shall be established in the midst of My people. 17 But if they do not obey, I will utterly pluck up and destroy that nation," says the Lord.

Commentary on Jeremiah 12:14-17
(Read Jeremiah 12:14-17)
The Lord would plead the cause of his people against their evil neighbours. Yet he would afterwards show mercy to those nations, when they should learn true religion. This seems to look forward to the times when the fulness of the Gentiles shall come in. Those who would have their lot with God's people, and a last end like theirs, must learn their ways, and walk in them.
