Genesis 2:20-24

He gave names to all the various cattle, birds, and wild animals, but Adam could not find a fitting companion that corresponded to him. So YAHWEH-God caused Adam to fall into a deep trance, and while he slept, he took a portion of Adam’s side and closed its place with flesh. Then YAHWEH-God used the portion of Adam’s side and skillfully crafted a woman and presented her to him. Then Adam said: “At last! One like me! Her bones were formed from my bones, and her flesh from my flesh! This one will be called ‘Woman,’ for she was taken from man.” For this reason, a man leaves his father and his mother to be unselfishly attached to his wife. They become one flesh as a new family!
