Mark 10:6-9 But at the beginning of the creation God made them male and female:

Geneva⁽ⁱ⁾ ⁶ But at the beginning of the creation God made them male and female: ⁷ For this cause shall man leaue his father and mother, and cleaue vnto his wife. ⁸ And they twaine shalbe one flesh: so that they are no more twaine, but one flesh. ⁹ Therefore, what God hath coupled together, let not man separate.
