Isaiah 31:3

Now, the Egyptians are men, and not God, that is, on the one hand were finite, powerless creatures, on the other the almighty God; and their horses flesh and not spirit, not endowed with the power of spirit beings, but only weak and perishable flesh. When the Lord shall stretch out His hand, make use of His almighty power, both he that helpeth shall fall, namely, Egypt, and he that is holpen, namely, Judah, shall fall down, the helper stumbling and he who accepts the help being carried down to the ground in his fall, and they all shall fail together.
