Genesis 2:17-18, 21-23

but of the tree of the knowledge of good and evil, thou shalt not eat of it: for in the day that thou eatest thereof thou shalt surely die. And Jehovah God said, It is not good that the man should be alone; I will make him a help meet for him.

And Jehovah God caused a deep sleep to fall upon the man, and he slept; and he took one of his ribs, and closed up the flesh instead thereof: and the rib, which Jehovah God had taken from the man, made he a woman, and brought her unto the man. And the man 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.
