Malachi 2:13-15

This is another thing you do: you cover the altar of the LORD with tears, with [your own] weeping and sighing, because the LORD no longer regards your offering or accepts it with favor from your hand. But you say, “Why [does He reject it]?” Because the LORD has been a witness between you and the wife of your youth, against whom you have dealt treacherously. Yet she is your marriage companion and the wife of your covenant [made by your vows]. But not one has done so who has a remnant of the Spirit. And what did that one do while seeking a godly offspring? Take heed then to your spirit, and let no one deal treacherously against the wife of your youth.
