14 Thus saith Jehovah against all mine evil neighbours, that touch the inheritance which I have caused my people Israel to inherit: Behold, I will pluck them up out of their land, and pluck out the house of Judah from among them. 15 And it shall come to pass, after I have plucked them up, I will return, and have compassion on them, and will bring them back, each one to his inheritance, and each one to his land. 16 And it shall come to pass, if they will diligently learn the ways of my people, to swear by my name, [As] Jehovah liveth—even as they taught my people to swear by Baal—they shall be built up in the midst of my people. 17 And if they will not obey, I will utterly pluck up and destroy that nation, saith Jehovah.
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.
