Mark 10:9

‹But from the beginning of the creation God made them male and female.›

‹For this cause shall a man leave his father and mother, and cleave to his wife;›

‹And they twain shall be one flesh: so then they are no more twain, but one flesh.›

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

And he saith unto them, ‹Whosoever shall put away his wife, and marry another, committeth adultery against her.›

‹And if a woman shall put away her husband, and be married to another, she committeth adultery.›
