(3) The Egyptians are men . . .--We hear again the key-note of Isaiah's teaching. The true strength of a nation lay in its spiritual, not in its material, greatness: in seeking the Holy One of Israel by practising holiness. Without that condition the alliance with Egypt would be fatal both to those that sought for help and those who gave it.

Verse 3. - Now the Egyptians are men, and not God. Judah relied on Pharaoh, as on a sort of God, which indeed he was considered in his own country ('Records of the Past,' vol. 6. p. 145, I. 320; p. 148, 1.418, etc.). Isaiah asserts the contrary in the strongest way: the Egyptians, one and all, are men - mere men; and "there is no help in them" (Psalm 146:3). Their horses flesh, and not spirit. The horses, on which so much reliance was placed, were mere animals, subject to all the weakness of the animal nature, not spirit-horses, with a life and vigor of their own, by which they could be a real tower of strength to those on whose side they ranged themselves. They all shall fail together; i.e. the helpers and the helped (compare the concluding clauses of ver. 2).

31:1-5 God will oppose the help sought from workers of iniquity. Sinners may be convicted of folly by plain and self-evident truths, which they cannot deny, but will not believe. There is no escaping the judgments of God; and evil pursues sinners. The Lord of hosts will come down to fight for Mount Zion. The Lion of the tribe of Judah will appear for the defence of his church. And as birds hovering over their young ones to protect them, with such compassion and affection will the Lord of hosts defend Jerusalem. He will so defend it, as to secure its safety.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 Psalm 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.
