Genesis 2:22-25

The LORD God used the rib from the man to make a woman, and then he brought the woman to the man. And the man said, “Now, this is someone whose bones came from my bones, whose body came from my body. I will call her ‘woman,’ because she was taken out of man.” So a man will leave his father and mother and be united with his wife, and the two will become one body. The man and his wife were naked, but they were not ashamed.
