14 This is what the Lord has said against all my evil neighbours, who put their hands on the heritage which I gave my people Israel: See, I will have them uprooted from their land, uprooting the people of Judah from among them. 15 And it will come about that, after they have been uprooted, I will again have pity on them; and I will take them back, every man to his heritage and every man to his land. 16 And it will be that, if they give their minds to learning the ways of my people, using my name in their oaths, By the living Lord; as they have been teaching my people to take oaths by the Baal; then their place will be made certain among my people. 17 But if they will not give ear, then I will have that nation uprooted, and given to destruction, 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.
