Mark 10:5-9
Mark 10:5-9 ESV
And Jesus said to them, “Because of your hardness of heart he wrote you this commandment. But from the beginning of creation, ‘God made them male and female.’ ‘Therefore a man shall leave his father and mother and hold fast to his wife, and the two shall become one flesh.’ So they are no longer two but one flesh. What therefore God has joined together, let not man separate.”
