Mark 10:2-9 King James Version (KJV)
2 And the Pharisees came to him, and asked him, Is it lawful for a man to put away his wife? tempting him.
3 And he answered and said unto them, What did Moses command you?
4 And they said, Moses suffered to write a bill of divorcement, and to put her away.
5 And Jesus answered and said unto them, For the hardness of your heart he wrote you this precept.
6 But from the beginning of the creation God made them male and female.
7 For this cause shall a man leave his father and mother, and cleave to his wife;
8 And they twain shall be one flesh: so then they are no more twain, but one flesh.
9 What therefore God hath joined together, let not man put asunder.
