The title of this psalm is apparently a composite, the usual "Psalm of David" having been enlarged by the awkward insertion of "A Song at the Dedication of the House," which probably indicates its later liturgical use, and not its first destination. Its occasion was evidently a deliverance from grave peril; and, whilst its tone is strikingly inappropriate if it had been composed for the inauguration of temple, tabernacle, or palace, one can understand how the venerable words, which praised Jehovah for swift deliverance from impending destruction, would be felt to fit the circumstances and emotions of the time when the Temple, profaned by the mad acts of Antiochus Epiphanes, was purified and the ceremonial worship restored. Never had Israel seemed nearer going down to the pit; never had deliverance come more suddenly and completely. The intrusive title is best explained as dating from that time and indicating the use then found for the song. It is an outpouring of thankfulness, and mainly a leaf from the psalmist's autobiography, interrupted only by a call to all who share Jehovah's favour to help the single voice to praise Him (vv. 4, 5). The familiar arrangement in pairs of verses is slightly broken twice, vv. 1-3 being linked together as a kind of prelude and vv. 8-10 as a repetition of the singer's prayer. His praise breaks the barrier of silence and rushes out in a flood. The very first word tells of his exuberant thankfulness, and stands in striking relation to God's act which evokes it. Jehovah has raised him from the very sides of the pit, and therefore what shall he do but exalt Jehovah by praise and commemoration of His deeds? The song runs over in varying expressions for the one deliverance, which is designated as lifting up, disappointment of the malignant joy of enemies, healing, rescue from Sheol and the company who descend thither, by restoration to life. Possibly the prose fact was recovery from sickness, but the metaphor of healing is so frequent that the literal use of the word here is questionable. As Calvin remarks, sackcloth (ver. 11) is not a sick man's garb. These glad repetitions of the one thought in various forms indicate how deeply moved the singer was, and how lovingly he brooded over his deliverance. A heart truly penetrated with thankfulness delights to turn its blessings round and round, and see how prismatic lights play on their facets, as on revolving diamonds. The same warmth of feeling, which glows in the reiterated celebration of deliverance, impels to the frequent direct mention of Jehovah. Each verse has that name set on it as a seal, and the central one of the three (ver. 2), not content with it only, grasps Him as "my God," manifested as such with renewed and deepened tenderness by the recent fact that "I cried loudly unto Thee, and Thou healedst me." The best result of God's goodness is a firmer assurance of a personal relation to Him. "This is
