Isaiah 30:3

Therefore shall the strength of Pharaoh be your shame,.... They should be disappointed of the help and assistance they expected from him, and so be ashamed of their ally, and of confidence in him:

and the trust in the shadow of Egypt [your] confusion; they should be confounded, when they should find themselves unsupported by the Egyptians, in whom they put their confidence; so all such that trust in the creature, or in an arm of flesh, sooner or later are ashamed and confounded; but those that trust in the Lord never are, neither in this world, nor in that to come.
