The world could spare many a large book better than this sunny little psalm. It has dried many tears and supplied the mould into which many hearts have poured their peaceful faith. To suppose that the speaker is the personified nation chills the whole. The tone is too intense not to be the outcome of personal experience, however admissible the application to the nation may be as secondary. No doubt Jehovah is the Shepherd of Israel in several Asaphite psalms and in Jeremiah; but, notwithstanding great authorities, I cannot persuade myself that the voice which comes so straight to the heart did not come from the heart of a brother speaking across the centuries his own personal emotions, which are universal just because they are individual. It is the pure utterance of personal trust in Jehovah, darkened by no fears or complaints and so perfectly at rest that it has nothing more to ask. For the time desire is stilled in satisfaction. One tone, and that the most blessed which can sound in a life, is heard through the whole. It is the psalm of quiet trust, undisturbed even by its joy, which is quiet too. The fire glows, but does not flame or crackle. The one thought is expanded in two kindred images: that of the shepherd and that of the host. The same ideas are substantially repeated under both forms. The lovely series of vivid pictures, each but a clause long, but clear-cut in that small compass, like the fine work incised on a gem, combines with the depth and simplicity of the religious emotion expressed, to lay this sweet psalm on all hearts. Vv. 1-4 present the realities of the devout life under the image of the Divine Shepherd and His lamb.
