Isaiah 30:5

5 but they will be put to shame, because Egypt is useless to them. It will give no help and will be of no use; it will cause them only shame and embarrassment."

Isaiah 30:5 Meaning and Commentary

Isaiah 30:5

They were all ashamed of a people [that] could not profit
them
The princes, the ambassadors that were sent unto them, and the king or people, or both, that sent them, who hoped for and expected great things from them, but, being disappointed, were filled with shame; because either the Egyptians, who are the people here meant, either could not help them, or would not, not daring to engage with so powerful an enemy as the Assyrian monarch, which is illustrated and confirmed by repeating the same, and using other words: nor be an help, nor profit, but a shame, and also a reproach:
so far from being of any advantage to them, by helping and assisting them against their enemy, wanting either inclination or capacity, or both, that it not only turned to their shame, but even was matter of reproach to them, that ever they made any application to them, or placed any confidence in them for help.

Isaiah 30:5 In-Context

3 But hiding in Egypt will bring you only shame; Egypt's protection will only disappoint you.

4 Your officers have gone to Zoan, and your messengers have gone to Hanes,

5 but they will be put to shame, because Egypt is useless to them. It will give no help and will be of no use; it will cause them only shame and embarrassment."

6 This is a message about the animals in southern Judah: full of lions and lionesses, poisonous snakes and darting snakes. The messengers travel through there with their wealth on the backs of donkeys and their treasure on the backs of camels. They carry them to a nation that cannot help them,

7 to Egypt whose help is useless. So I call that country Rahab the Do-Nothing.
