Psalms 17:11-12

They have compassed us in our steps In all our ways. We go from place to place: we flee for safety to rocks, caves, and woods; but whithersoever we go they are at hand, and ready to surround us. See an instance of this 1 Samuel 23:26. They have set their eyes Namely, upon or against us. They have discovered us, and keep their eyes fixed upon us, that we may not escape, or as intending to shoot at us with their arrows. Bowing down to the earth Couching and casting themselves down upon the earth, that they may not be discovered, and so may watch the fittest opportunity to surprise us. Which sense is favoured by the next verse, and by comparing Psalms 10:10. The Hebrew, however, לנשׂות בארצ, lintoth baaretz, may be rendered, to cast us down to the earth, that is, They have fixed their eyes upon us, in order that they may watch their opportunity to lay us prostrate on the ground, and destroy us. Like a lion, greedy of his prey Which is hungry, and therefore cruel. “The similitude of a lion, either roaming abroad in quest of his prey, or couching in secret, ready to spring upon it, the moment it comes within his reach, is often employed by David, to describe the power and malice of his enemies. Christians cannot forget that they likewise have an adversary of the same nature and character; one ever seeking whom, and contriving how, he may devour.” Horne.
