Bereshis 2:18-25

And HASHEM Elohim said, It is not tov that the adam should be alone; I will make him an ezer (a helper) suitable for him. And out of the adamah HASHEM Elohim formed every beast of the sadeh, and every oph HaShomayim; and brought them unto the adam to see what he would name them; and whatsoever the adam named kol nefesh chayyah, that was shmo. And the adam gave shemot to all behemah, and to the oph HaShomayim, and to every beast of the sadeh; but for Adam there was not found an ezer for him. And HASHEM Elohim caused a tardemah (deep sleep) to fall upon the adam, and he slept; and He took from one of his tzalelot (sides, ribs), and closed up the basar in the place thereof; And the tzela (rib), which HASHEM Elohim had taken from the adam, made He an isha, and brought her unto the adam. And the adam said, This is now etzem of my etzem, and basar of my basar; she shall be called Isha, because she was taken out of Ish. Therefore shall an ish leave his av and his em, and shall cleave unto his isha: and they shall be basar echad. And they were both arummim (naked ones), the adam and his isha, and were not ashamed.
