Isaiah 20:3-6

It was gracious in the Lord, to explain the meaning of this typical representation, that no misapplication might be made of it. And while the lesson tended to humble both nations, Egypt and Ethiopia, as the Lord designed it; the Lord's mercy to his people Israel, was the more signally displayed. Surely Israel might learn therefrom, how unsuitable an arm of flesh must be to support them, when a whole nation was thus led into captivity itself. Reader! the same lesson is in force even now; whew shall we look for aid in the hour of necessity, but to the Lord our righteousness? Truly in vain, saith the prophet, is salvation hoped for from the hills, and from the multitude of mountains; truly in the Lord our God is the salvation of Israel; Jeremiah 3:23.
