Malachi 2:12-14

As for the man who does this, may the LORD cut off from the tents of Jacob to the last man those who do this [evil thing], awake and aware, even the one who brings an offering to the LORD of hosts. 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].
