Genesis 2:22-26

And the rib, which the LORD God had taken from man, made he a woman, and brought her unto the man.

And 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.

Therefore shall a man leave his father and his mother, and shall cleave unto his wife: and they shall be one flesh.

And they were both naked, the man and his wife, and were not ashamed.
