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.

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.
