Genesis 2:24 Therefore a man will leave his father and his mother, and will join with his wife, and they will be one flesh.
This is the book of the generations of Adam. In the day that God created man, he made him in God's likeness. He created them male and female, and blessed them, and called their name "Adam," in the day when they were created.
Mark 10:6-7 “But from the beginning, God made them male and female.
Because of this a man shall leave his father and mother and cleave to his wife.”
The nature of the woman that God created is...his nature!
