Genesis 2:21-24

21So the Lord God caused the man to sleep. While the man was sleeping, God took a rib from the man. Then he closed up the place in his body and he covered it again.

22The Lord God used the man's rib to make a woman. He brought the woman to the man.

23Then the man said, ‘Finally, this is someone who is right for me. She has bones that are taken from my bones. Her body comes from my body. I will call her “woman” because God used me, a man, to make her.’

24Because of this, when a man marries, he leaves his father and his mother. Instead, God joins the man and his wife together. The two people become as one body.
