Mark 10:5-8

King James Version

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.
