Leviticus 17

In the case of the human person: first its body is created from the dust, and afterward the power of life is given to it, and this is the being of the soul. Accordingly Moses said about the beasts, "Its blood is its life." But in the case of the human person its being is incorporeal and immortal and has a great superiority over the body, to the same extent as incorporeal form surpasses the corporeal.
