Thou compassest my path; thou watchest me on every side, and therefore discernest every step which I take. It is a metaphor either from huntsmen watching all the motions and lurking-places of wild beasts, that they may catch them; or from soldiers besieging their enemies in a city, and setting watches round about them. My lying down; me, when I lie down in my bed, where men oft contrive what they execute in the day time.
