Isaiah 31:3
Now the Egyptians are men, and not God; and their horses flesh, and not spirit. When the LORD shall stretch out his hand, both he that helpeth shall fall, and he that is holpen shall fall down, and they all shall fail together.
Now the Egyptians are men, and not God,.... Be it that they are mighty, they are not mighty, as God is; and indeed they are but frail, feeble, mortal, and mutable men, and therefore not to be trusted in, and depended on; or to be put upon an equality with God, and even to be preferred to him, as they were by the Jews; and of what use and service could they be unto them, seeing God was against them?
and their horses flesh, and not spirit; only flesh, without an immortal soul or spirit, which man has; and therefore a foolish thing in man to trust in them, who must be entirely guided and directed by them; and much less angelic spirits, or like them, which are incorporeal, invisible, and exceedingly mighty and powerful, which excel all creatures in strength, and are called the mighty angels; these are God's cavalry, his horses and chariots; see Psalms 68:17 Habakkuk 3:8 and what mighty things have been done by them, even by a single one? Witness the destruction of the Assyrian army, in one night, by one of them; wherefore the Egyptian cavalry was not to be named with them {q}:
When the LORD shall stretch out his hand; as soon as he does it, before he strikes, and when he does this in order to it:
both he that helpeth shall fall; or "stumble", take a false step; meaning the Egyptians, sent for and come forth to help the Jews; but, stumbling and falling themselves, would be but poor assistants to them. Aben Ezra interprets this of the king of Assyria destroying the Egyptians, when he came to Jerusalem:
and he that is holpen shall fall down; the Jews, helped by the Egyptians, who should fall, and be destroyed, though not now; yet hereafter by the Chaldeans, as they were:
and they all shall fail together; both the Egyptians and the Jews.
{q} So Ben Melech interprets "spirit" of an angel, as he does the word "God" in the preceding clause.
