Genesis 2:7, 21-22

then the LORD God formed the man of dust from the ground and breathed into his nostrils the breath of life, and the man became a living creature.

So the LORD God caused a deep sleep to fall upon the man, and while he slept took one of his ribs and closed up its place with flesh. And the rib that the LORD God had taken from the man he made into a woman and brought her to the man.
