Calvin says that the authorship of this psalm is uncertain, but that it is abundantly clear that it was composed by any one rather than David, and that its plaintive contents suit best the time when the savage tyranny of Antiochus raged. No period corresponds to the situation which makes the background of the psalm so completely as the Maccabean, for only then could it be truly said that national calamities fell because of the nation's rigid monotheism. Other epochs have been thought of, so as to avoid the necessity of recognising Maccabean psalms, but none of them can be said to meet the conditions described in the psalm. The choice lies between accepting the Maccabean date and giving up the attempt to fix one at all. Objections to that late date based upon the history of the completion of the canon take for granted more accurate and complete knowledge of a very obscure subject than is possessed, and do not seem strong enough to negative the indications arising from the very unique fact, asserted in the psalm, that the nation was persecuted for its faith and engaged in a religious war. The psalm falls into four parts: a wistful look backwards to days already "old," when God fought for them (vv. 1-8); a sad contrast in present oppression (vv. 9-16); a profession of unfaltering national adherence to the covenant notwithstanding all these ills (vv. 17-22); and a fervent cry to a God who seems asleep to awake and rescue His martyred people (vv. 23-26). The first part (vv. 1-8) recalls the fact that shone so brightly in all the past, the continual exercise of Divine power giving victory to their weakness, and builds thereon a prayer that the same law of His providence might be fulfilled now. The bitter side of the retrospect forces itself into consciousness in the next part, but here Memory is the handmaid of Faith. The whole process of the Exodus and conquest of Canaan is gathered up as one great "work" of God's hand. The former inhabitants of the land were uprooted like old trees, to give room for planting the "vine out of Egypt." Two stages in the settlement are distinguished in ver. 2: first came the "planting" and next the growth; for the phrase "didst spread them forth" carries on the metaphor of the tree, and expresses the extension of its roots and branches. The ascription of victory to God is made more emphatic by the negatives in ver. 3, which take away all credit of it from the people's own weapons or strength. The consciousness of our own impotence must accompany adequate recognition of God's agency in our deliverances. The conceit of our own power blinds our vision of His working hand. But what moved His power? No merit of man's, but the infinite free grace of God's heart. "The light of Thy face" is the symbol of God's loving regard, and the deepest truth as to His acts of favour is that they are the outcome of His own merciful nature. He is His own motive. "Thou hadst
