Bereshis 2:18-20

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.
