Genesis 2:20-25

And the man gave names to all the livestock, and to the birds of the air, and to every animal of the field; but for Adam there was not found a helper [that was] suitable (a companion) for him. So the LORD God caused a deep sleep to fall upon Adam; and while he slept, He took one of his ribs and closed up the flesh at that place. And the rib which the LORD God had taken from the man He made (fashioned, formed) into a woman, and He brought her and presented her to the man. Then Adam said, “This is now bone of my bones, And flesh of my flesh; She shall be called Woman, Because she was taken out of Man.” For this reason a man shall leave his father and his mother, and shall be joined to his wife; and they shall become one flesh. [Matt 19:5; 1 Cor 6:16; Eph 5:31-33] And the man and his wife were both naked and were not ashamed or embarrassed.
