Matthew 19:4-6

4 He answered, "Have you not read that he who made them from the beginning made them male and female,
5 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'?
6 So they are no longer two but one flesh. What therefore God has joined together, let not man put asunder."
