Matthew 19:1-6 RSV

1 Now when Jesus had finished these sayings, he went away from Galilee and entered the region of Judea beyond the Jordan;
2 and large crowds followed him, and he healed them there.
3 And Pharisees came up to him and tested him by asking, "Is it lawful to divorce one's wife for any cause?"
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."
