Mateus 5

31 Again Yeshua [God is Salvation] said to his disciples: "You have heard what was said to those of long ago that everyone who leaves his wife and divorces her is to give her a bill of divorce",

32 "And I say to you that everyone who leaves his wife is to give her a bill of divorce. But concerning adultery. he is the one who commits adultery and he who takes her commits adultery".
