²⁷ So God created man in his own image,
    in the image of God he created him;
    male and female he created them.

Genesis 2:24 (ESV)

²⁴ Therefore a man shall leave his father and his mother and hold fast to his wife, and they shall become one flesh.

Matthew 19:3-6 (ESV)

³ And Pharisees came up to him and tested him by asking, “Is it lawful to divorce one's wife for any cause?” ⁴ He answered, “Have you not read that he who created them from the beginning made them male and female, ⁵ and said, ‘Therefore a man shall leave his father and his mother and hold fast to his wife, and the two shall become one flesh’? ⁶ So they are no longer two but one flesh. What therefore God has joined together, let not man separate.”
