Jeremiah 3:1

They say, literally, "Saying," God Himself being the subject of the sentence. If a man put away his wife, and she go from him and become another man's, shall he return unto her again? Such dismissals were sometimes practiced among the Jews, but it was then unlawful for a man to take back his former wife, Deuteronomy 24:1. Shall not that land be greatly polluted? on account of the abomination connected with such practices. But thou hast played the harlot with many lovers, none of them being her lawful husband; yet, in spite of the fact that it is not in accordance with legal regulations, return again to Me, saith the Lord, for He was ready to show mercy even under such adverse conditions.
