Furthermore it has been said, whoever divorces his wife, let him give her a certificate of divorce,. 32 But I say to you that whoever divorces his wife for any reason except sexual immorality causes her to commit adultery; and whoever marries a woman who is divorced commits adultery. Mathew 5: 31-32
