Charles H. Spurgeon on Psalms 55:1

Hide not thyself from my supplication. A figure taken from the conduct of a king who debars an offender from seeing his face (2Sa 14:24), or from an enemy, who conceals himself from the ox, etc.; that is, pretends not to see it, and goes away, leaving it (see De 22:1,3,4 Isa 58:7); or, from a false friend, or an unkind person, who, foreseeing that he may be entreated by a miserable and needy man, will not let himself be seen, but seeks to make his escape. Martin Geier, 1614-1681.
