Genesis 2:18-21

Then YAHWEH-God said, “It is not good for the man to be alone. Therefore, I will fashion a suitable partner to be his help and strength.” For YAHWEH-God had formed from the soil every animal of the field and every bird of the air and brought them before the man to see what he would call them. So, whatever the man called the living creature, that was its name. 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.
