Matthew 19:3-6

Some Pharisees came to Jesus, testing Him and asking, “Is it lawful for a man to divorce his wife for any reason at all?” And He answered and said, “Have you not read that He who created them from the beginning MADE THEM MALE AND FEMALE, and said, ‘FOR THIS REASON A MAN SHALL LEAVE HIS FATHER AND MOTHER AND BE JOINED TO HIS WIFE, AND THE TWO SHALL BECOME ONE FLESH’? So they are no longer two, but one flesh. What therefore God has joined together, let no man separate.”
