Genesis 2:22-25 NIV

[22] Then the LORD God made a woman from the rib he had taken out of the man, and he brought her to the man. [23] The man said, “This is now bone of my bones and flesh of my flesh; she shall be called ‘woman,’ for she was taken out of man.” [24] That is why a man leaves his father and mother and is united to his wife, and they become one flesh. [25] Adam and his wife were both naked, and they felt no shame.
