14 Thus says the Lord concerning all my evil neighbors who touch the heritage that I have given my people Israel to inherit: I am about to pluck them up from their land, and I will pluck up the house of Judah from among them. 15 And after I have plucked them up, I will again have compassion on them, and I will bring them again to their heritage and to their land, everyone of them. 16 And then, if they will diligently learn 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 built up in the midst of my people. 17 But if any nation will not listen, then I will completely uproot it and destroy it, says the Lord.
Matthew Henry's Commentary on Jeremiah 12:14-17
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.
