Ewald's widely accepted view that this psalm is a composite of two fragments rests on a somewhat exaggerated estimate of the differences in tone and structure of the parts. These are obvious, but do not demand the hypothesis of compilation; and the original author has as good a right to be credited with the uniting thought as the supposed editor has. The usually alleged occasion of the psalm fits its tone so well and gives such appropriateness to some of its phrases that stronger reasons than are forthcoming are required to negative it. The account in 2 Sam. vi. tells of exuberant enthusiasm and joy, of which some echo sounds in the psalm. It is a processional hymn, celebrating Jehovah's entrance to His house; and that one event, apprehended on its two sides, informs the whole. Hence the two halves have the same interchange of question and answer, and the two questions correspond, the one inquiring the character of the men who dare dwell with God, the other the name of the God who dwells with men. The procession is climbing the steep to the gates of the ancient Jebusite fortress, recently won by David. As it climbs, the song proclaims Jehovah as the universal Lord, basing the truth of His special dwelling in Zion upon that of His world-wide rule. The question, so fitting the lips of the climbers, is asked, possibly in solo, and the answer describing the qualifications of true worshippers, and possibly choral (vv. 3-6), is followed by a long-drawn musical interlude. Now the barred gates are reached. A voice summons them to open. The guards within, or possibly the gates themselves, endowed by the poet with consciousness and speech, ask who thus demands entrance. The answer is a triumphant shout from the procession. But the question is repeated, as if to allow of the still fuller reiteration of Jehovah's name, which shakes the grey walls; and then, with clang of trumpets and clash of cymbals, the ancient portals creak open, and Jehovah "enters into His rest, He and the ark of His strength." Jehovah's dwelling on Zion did not mean His desertion of the rest of the world, nor did His choice of Israel imply His abdication of rule over, or withdrawal of blessings from, the nations. The light which glorified the bare hilltop, where the Ark rested, was reflected thence over all the world. "The glory" was there concentrated, not confined. This psalm guards against all superstitious misconceptions, and protests against national narrowness, in exactly the same way as Exod. xix. 5 bases Israel's selection from among all peoples on the fact that "all the earth is Mine."
