Isaiah 30:5
They were all ashamed of a people that could not profit them, nor be an help nor profit, but a shame, and also a reproach.
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.
