Mark 10:8

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.

¹⁰  And in the house his disciples asked him again of the same matter.
