Matthew 19
4 Ref And he said in answer, Have you not seen in the Writings, that he who made them at the first made them male and female, and said,
5 Ref For this cause will a man go away from his father and mother, and be joined to his wife; and the two will become one flesh?
6 Ref So that they are no longer two, but one flesh. Then let not that which has been joined by God be parted by man.
