Divorce
"It has been said, 'Anyone who divorces his wife must give her a certificate of divorce.'"
Matthew 5:31
New International Version
"A ruler questioned Him, saying, "Good Teacher, what shall I do to inherit eternal life?" And Jesus said to him, "Why do you call Me good? No one is good except God alone. You know the commandments, 'Do not commit adultery, do not murder, do not steal, do not bear false witness, honor your father and mother.'""
"But a man who commits adultery lacks judgment; whoever does so destroys himself."
