Wherefore doth the wicked, &c.— We may collect from hence, that there were two kinds of infidels at the time this psalm was written; one of which made God a sort of Epicurean deity, and supposed him not to concern himself with the moral government of the world; the other altogether denied his being. See Psalms 10:4.
