Therefore shall the strength of Pharaoh be your shame - (see the note at Isaiah 20:5).

Your confusion - Hebrew, 'For reproach.' It would either occur that the Egyptians "would" not enter into an alliance; or that if they did, they "could" not defend them, and in either case it would be the source of deep regret and shame.

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.

Therefore shall the strength of Pharaoh be your shame, and the trust in the shadow of Egypt your confusion.

3. shame-disappointment. Egypt, weakened by its internal dissensions, can give no solid help.

30:1-7 It was often the fault and folly of the Jews, that when troubled by their neighbours on one side, they sought for succour from others, instead of looking up to God. Nor can we avoid the dreadful consequences of adding sin to sin, but by making the righteousness of Christ our refuge, and seeking for the sanctification of the Holy Spirit. Men have always been prone to lean to their own understandings, but this will end in their shame and misery. They would not trust in God. They took much pains to gain the Egyptians. The riches so spent turned to a bad account. See what dangers men run into who forsake God to follow their carnal confidences. The Creator is the Rock of ages, the creature a broken reed; we cannot expect too little from man, or too much from God. Our strength is to sit still, in humble dependence upon God and his goodness, and quiet submission to his will.
