Charles H. Spurgeon on Psalms 146:3

Put not your trust in princes, etc. True, may some say, it were a folly to trust in weak princes, to trust in them for help who have no power to help; but we will apply to mighty princes; we hope there is help in them. No; those words, "in whom there is no help", are not a distinction of weak princes, from strong, but a conclusion that there is no help in the strongest. That's strange. What? No help in strong princes! If he had said, no help in mean men, carnal reason would have consented; but when he saith, "Trust not in princes, nor in any son of man", one or other, who can believe this? Yet this is divine truth; we may write insufficiency, insufficiency, and a third time, insufficiency, upon them all; the close of this verse may be their motto, There is no help, in them. —Joseph Caryl.
