Charles H. Spurgeon on Psalms 36:11

Let not the foot of pride come against me. The general prayer is here turned into a particular and personal one for himself. Pride is the devil's sin. Good men may well be afraid of proud men, for the serpent's seed will never cease to bite the heel of the godly. Fain would proud scoffers spurn the saints or trample them under foot: against their malice prayer lifts up her voice. No foot shall come upon us, no hand shall prevail against us, while Jehovah is on our side. Let not the hand of the wicked remove me. Suffer me not to be driven about as a fugitive, nor torn from my place like an uprooted tree. Violence with both hand and foot, with means fair and means foul, strove to overthrow the psalmist, but he resorts to his great Patron, and sings a song of triumph in anticipation of the defeat of his foes.
