But life has another aspect than these two--rest and toil; and the guidance into danger and sorrow is as tender as its other forms are. The singular word rendered "shadow of death" should probably simply be "gloomy darkness," such, for instance, as in the shaft of a mine (Job xxviii. 3). But, even if the former rendering is retained, it is not to be interpreted as meaning actual death. No wise forward look can ignore the possibility of many sorrows and the certainty of some. Hope has ever something of dread in her eyes. The road will not be always bright and smooth, but will sometimes plunge down into grim cañons, where no sunbeams reach. But even that anticipation may be calm. "Thou art with me" is enough. He who guides into the gorge will guide through it. It is not a _cul de sac_, shut in with precipices at the far end; but it opens out on shining table-lands, where there is greener pasture. The rod and staff seem to be two names for one instrument, which was used both to beat off predatory animals and to direct the sheep. The two synonyms and the appended pronoun express by their redundancy the full confidence of the psalmist. He will not fear, though there are grounds enough for terror, in the dark valley; and though sense prompts him to dread, he conquers fear because he trusts. "Comfort" suggests a struggle, or, as Calvin says, "Quorsum enim consolatio ipsa, nisi quia metus eum solicitat?" The second image of the Divine Host and His guest is expanded in vv. 5, 6. The ideas are substantially the same as in the first part. Repose and provision, danger and change, again fill the foreground; and again there is forecast of a more remote future. But all is intensified, the need and the supply being painted in stronger colours and the hope being brighter. The devout man is God's guest while he marches through foes, and travels towards perpetual repose in the house of Jehovah.
