Jeremiah 12:15-16

MSTC(i) 15 And when I have rooted them out, I will be at one with them again, and will have mercy upon them: and bring them again, every man to his own heritage, and into his land. 16 And if they, namely that trouble my people, will learn the ways of them, to swear by my name, 'The LORD liveth' - like as they learned my people to swear by Baal - then shall they be reckoned among my people.
