Matthew 19:3

1And it came to pass, that when Jesus had finished these sayings, he departed from Galilee, and came into the coasts of Judaea beyond Jordan;

2And great multitudes followed him; and he healed them there.

3The Pharisees also came unto him, tempting him, and saying unto him, Is it lawful for a man to put away his wife for every cause?

4And he answered and said unto them, Have ye not read, that he which made them at the beginning made them male and female,

5And said, For this cause shall a man leave father and mother, and shall cleave to his wife: and they twain shall be one flesh?
