And what follows in the writings of Moses I quoted and explained; “from which I have demonstrated,” I said, “that He who is described as God appeared to Abraham, to Isaac, and to Jacob, and the other patriarchs, was appointed under the authority of the Father and Lord, and ministers to His will.” Then I went on to say what I had not said before: “And so, when the people desired to eat flesh, and Moses had lost faith in Him, who also there is called the Angel, and who promised that God would give them to satiety, He who is both God and the Angel, sent by the Father, is described as saying and doing these things.
