In the first strophe "Shepherd of Israel" reminds us of Jacob's blessing of Ephraim and Manasseh, in which he invoked "the God who shepherded me all my life long" to "bless the lads," and of the title in Gen. xlix. 24, "the shepherd, the stone of Israel." The comparison of the nation to a flock is characteristic of the Asaph psalms, and here refers to the guidance of the people at the Exodus. Delitzsch regards the notions of the earthly and heavenly sanctuary as being blended in the designation of God as sitting throned on the cherubim, but it is better to take the reference as being to His dwelling in the Temple. The word rendered "shine forth" occurs in Psalm l. 2, where it expresses His coming from "Zion," and so it does here. The same metaphor underlies the subsequent petition in ver. 3. In both God is thought of as light, and the manifestation of His delivering help is likened to the blazing out of the sun from behind a cloud. In reference to the mention of the tribes in ver. 2, we need only add to what has been already said, that the petitions of ver. 1, which look back to the wilderness marches, when the Ark led the van, naturally suggested the mention of the three tribes who were together reckoned as "the camp of Ephraim," and who, in the removal of the encampment, "set forth third"--that is, immediately in the rear of the tabernacle. The order of march explains not only the collocation here, but the use of the word "Before." Joseph and Benjamin were children of the same mother, and the schism which parted their descendants is, to the psalmist's faith, as transient as unnatural. Once again shall the old unity be seen, when the brothers' sons shall again dwell and fight side by side, and God shall again go forth before them for victory. The prayer of the refrain, "turn us," is not to be taken as for restoration from exile, which is negatived by the whole tone of the psalm, nor as for spiritual quickening, but simply asks for the return of the glories of ancient days. The petition that God would let His face shine upon the nation alludes to the priestly benediction (Numb. vi. 25), thus again carrying us back to the wilderness. Such a flashing forth is all that is needed to change blackest night into day. To be "saved" means here to be rescued from the assaults of hostile nations. The poet was sure that Israel's sole defence was God, and that one gleam of His face would shrivel up the strongest foes, like unclean, slimy creatures which writhe and die in sunshine. The same conviction is valid in a higher sphere. Whatever elevation of meaning is given to "saved," the condition of it is always this--the manifestation of God's face. That brings light into all dark hearts. To behold that light, and to walk in it, and to be transformed by beholding, as they are who lovingly and steadfastly gaze, is salvation.
