He does well here to attribute the flow of blood to

 Genesis ix. 8. 
 
the mass of flesh, combining two things appropriate to one another; but the essence of the mind he has not made to depend on any created thing, but has represented it as breathed into man by God from above. For, says Moses, "The Creator of the universe breathed into his face the breath of life, and man became a living soul," Genesis ii. 7. who also, it is recorded, was fashioned after the image of the Creator.
 So that the race of mankind also is twofold, the one being the race of those who live by the divine Spirit and reason; the other of those who exist according to blood and the pleasure of the flesh. This species is formed of the earth, but that other is an accurate copy of the divine image; and that description of us which is but fashioned clay, and which is kneaded up with blood, has need, in no slight degree, of assistance from God; on which account it is said, this Damascus of Eleazar. Genesis xv. 2. But the name Eleazar, being interpreted, means, "God is my helper." Since the mass of the body, which is filled with blood, being of itself easily dissolved and dead, has its existence through, and is kept alive by, the providence of God, who holds his arm and shield of defence over it, while our race cannot, by any resources of its own, exist in a state of firmness and safety for a single day.
 Do you not see that the second of the sons of Moses has also the same name as this man? For, "the name of the second," says the scripture, "was Eleazar." Exodus xviii. 4. And he adds the reason: "for the Lord has been my helper, and has delivered me out of the hand of Pharaoh." But those who are still companions of that life which owes its existence to blood, and which is appreciable by the outward senses, are attacked by that disposition which is such a formidable disperser of piety, by name Pharaoh; from whose sovereignty, full as it is of lawlessness and cruelty, it is impossible to escape, unless Eleazar be born in the soul, and unless one puts one’s hope of succour in the only Saviour.
