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

And the- strength of Pharao shall be to your confusion, and the confidence of the shadow of Egypt to your shame.

For to you the protection of Pharaoh shall be a shame, and the trust in the shadow of Egypt a confusion.

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

And the strength of Pharaoh will be your shame, and your hope in the shade of Egypt will come to nothing.

Therefore shall the stronghold of Pharaoh turn to your shame, and the shelter in the shadow of Egypt to your confusion.

And so, the strength of Pharaoh will be your confusion, and trust in the shadow of Egypt will be your disgrace.

Erit autem vobis fortitudo Pharaonis in pudorem, et fiducia in umbra Ægypti in ignominiam.

But to you shall the strength of Pharaoh be shame. He now shews what shall be the end of the wicked, who despise God and his word, and follow those schemes which are most agreeable to their own views. All that they undertake shall tend to their ruin. He threatens not only that they shall be disappointed of their hope, but also that they are seeking with great toil, destruction and ruin, from which they will gain nothing but sorrow and disgrace. To all wicked men it must unavoidably happen that, although for a time they appear to gain their object, and though everything succeeds to their wish, yet in the end all shall be ruinous to them. It is the just reward of their rashness, when they go beyond the limits of the word; for nothing that has been acquired by wicked and unlawful methods can be of advantage to any person. By way of admission he calls it "the strength of Pharaoh," as if he had said, "You think that you gain much protection from Pharaoh, but it will yield you reproach and disgrace. The shadow of Egypt, by which you hoped to be covered, will make you blush for shame." Accordingly, both expressions, "shame" and "disgrace," have the same meaning; and as chrphh, (chErpah,) [1] reproach, is a stronger expression than "shame," it is afterwards added for the purpose of bringing out the meaning more fully.

1 - The allusion is to the concluding clause of the fifth verse." -- Ed

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.

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