Exodus 4:3

But we know that prophecy expressed itself by things no less than by words. By words, and also by deeds, is the resurrection foretold. When Moses puts his hand into his bosom, and then draws it out again dead, and again puts his hand into his bosom, and plucks it out living, does not this apply as a presage to all mankind? inasmuch as those three signs denoted the threefold power of God: when it shall, first, in the appointed order, subdue to man the old serpent, the devil, however formidable; then, secondly, draw forth the flesh from the bosom of death; and then, at last, shall pursue all blood (shed) in judgment. …

Now, he says, the stars are the gods of destruction, which impose upon existent things the necessity of alterable generation. These, he says, Moses denominated serpents of the wilderness, which gnaw and utterly ruin those who imagined that they had crossed the Red Sea. To those, then, he says, who of the children of Israel were bitten in the wilderness, Moses exhibited the real and perfect serpent; and they who believed on this serpent were not bitten in the wilderness, that is, (were not assailed) by (evil) powers. No one therefore, he says, is there who is able to save and deliver those that come forth from Egypt, that is, from the body and from this world, unless alone the serpent that is perfect and replete with fulness. Upon this (serpent), he says, he who fixes his hope is not destroyed by the snakes of the wilderness, that is, by the gods of generation. …

11. For since the divine power administers the whole spiritual and corporeal creature, the waters of the sea are summoned and poured out upon the face of the earth on certain days of every year. But when this was done at the prayer of the holy Elijah; because so continued and long a course of fair weather had gone before, that men were famished; and because at that very hour, in which the servant of God prayed, the air itself had not, by any moist aspect, put forth signs of the coming rain; the divine power was apparent in the great and rapid showers that followed, and by which that miracle was granted and dispensed. …

4. “Remember Thou Thy congregation, which Thou hast possessed from the beginning” ( ver. 2 ). Can this by any means be the voice of the Gentiles? Hath He possessed the Gentiles from the beginning? Nay, but He hath possessed the seed of Abraham, the people of Israel even according to the flesh, born of the Patriarchs our fathers: of whom we have become the sons, not by coming out of their flesh, but by imitating their faith. But those, possessed by God from the beginning, what befell them? “Remember Thy congregation which Thou hast possessed from the beginning. Thou hast redeemed the rod of Thine inheritance.” That same congregation of Thine, being the rod of Thine inheritance, Thou hast redeemed. …

Thus Moses also first is in fear of the serpent, and not merely in fear, but even with much distress: and then he sees that strange thing come to pass. So these too, having first looked to perish, were then saved, that having confessed the danger, they might learn the greatness of the miracle.

74. Nor ought it to appear at all impro bable, that at the command of God the bones were fitted again to their joints, since we have numberless instances in which nature has obeyed the commands of heaven; as the earth was bidden to bring forth the green herb, and did bring it forth; as the rock at the touch of the rod gave forth water for the thirsting people; and the hard stone poured forth streams by the mercy of God for those parched with heat. What else did the rod changed into a serpent signify, than that at the will of God living things can be produced from those that are without life? Do you think it more incredible that bones should come together when bidden, than that streams should be turned back or the sea flee? For thus does the prophet testify: “The sea saw it and fled, Jordan was driven back.” Nor can there be any doubt about this fact, which was proved by the rescue of one …

51. Moses was holding a rod, he cast it down and it became a serpent. Again, he took hold of the tail of the serpent and it returned to the nature of a rod. You see that by virtue of the prophetic office there were two changes, of the nature both of the serpent and of the rod. The streams of Egypt were running with a pure flow of water; of a sudden from the veins of the sources blood began to burst forth, and none could drink of the river. Again, at the prophet’s prayer the blood ceased, and the nature of water returned. The people of the Hebrews were shut in on every side, hemmed in on the one hand by the Egyptians, on the other by the sea; Moses lifted up his rod, the water divided and hardened like walls, and a way for the feet appeared between the waves. Jordan being turned back, returned, contrary to nature, to the source of its stream. …
