Once more, the song passes, in ver. 30, to the wider truths taught by the personal deliverance. "Our God" takes the place of "my God"; and "all who take refuge in Him" are discerned as gathering, a shadowy crowd, round the solitary psalmist, and as sharing in his blessings. The large truths of these verses are the precious fruit of distress and deliverance. Both have cleared the singer's eyes to see, and tuned his lips to sing, a God whose doings are without a flaw, whose word is like pure gold without alloy or falsehood, whose ample protection shields all who flee to its shelter, who alone is God, the fountain of strength, who stands firm for ever, the inexpugnable defence and dwelling-place of men. This burst of pure adoration echoes the tones of the glorious beginning of the psalm. Happy they who, as the result of life's experience, solve "the riddle of this painful earth," with these firm and jubilant convictions as the very foundation of their being.
The remainder of the psalm (ver. 32 to end) describes the victorious campaign of the psalmist and the establishment of his kingdom. There is difficulty in determining the tenses of the verbs in some verses, and interpreters vary between pasts and futures. The inclination of the greater number of recent commentators is to carry the historical retrospect uninterruptedly through the whole context, which, as Hupfeld acknowledges, "allerdings das bequemste ist," and those who suppose occasional futures interspersed (as the R.V. and Hupfeld) differ in the places of their introduction. "Everything here is retrospective," says Delitzsch, and certainly that view is simplest and gives unity to the whole. The name of God is never mentioned in the entire section, except as vainly invoked by the flying foe. Not till the closing doxologies does it appear again, with the frequency which marks the middle part of the psalm. A similar sparse use of it characterises the description of the theophany. In both cases there is a peculiar force given by the stream of verbs without expressed nominatives. The hurrying clauses here vividly reproduce the haste of battle, and each falls like the blow of a battle mace wielded by a strong arm. The equipment of the king for the fight (vv. 32-36), the fierce assault, flight of the foe and their utter annihilation (vv. 37-42), the extension by conquest of the singer's kingdom (vv. 43, 44), successively pass before us as we listen to the panting words with the heat of battle in them; and all rises at last into exuberant praise, which re-echoes some strains of the introductory burst of thanksgiving.
Many mythologies have told how the gods arm their champions, but the psalmist reaches a loftier height than these. He ventures to think of God as doing the humble office of bracing on his girdle, but the girdle is itself strength. God, whose own "way is perfect" (ver. 30), makes His servant's "way" in some measure like His own; and though, no doubt, the figure must be interpreted in a manner congruous with its context, as chiefly implying "perfection" in regard to the purpose in hand—namely, warfare—we need not miss the deeper truth that God's soldiers are fitted for conflict by their "ways" being conformed to God's. This man's "strength was as the strength of ten, because his heart was pure." Strength and swiftness are the two characteristics of antique heroes, and God's gift bestowed both on the psalmist. Light of foot as a deer and able to climb to the robber forts perched on crags, as a chamois would, his hands deft, and his muscular arms strong to bend the bow which others could not use, he is the ideal of a warrior of old; and all these natural powers he again ascribes to God's gift. A goddess gave Achilles his wondrous shield, but what was it to that which God binds upon this warrior's arm? As his girdle was strength, and not merely a means of strength, his shield is salvation, and not merely a means of safety. The fact that God purposes to save and does act for saving is the defence against all dangers and enemies. It is the same deep truth as the prophet expresses by making "salvation" the walls and bulwarks of the strong city where the righteous nation dwells in peace. God does not thus arm His servant and then send him out alone to fight as he can, but "Thy right hand holds me up." What assailant can beat him down, if that hand is under his armpit to support him? The beautiful rendering of the A.V., "Thy gentleness," scarcely conveys the meaning, and weakens the antithesis with the psalmist's "greatness," which is brought out by translating "Thy lowliness," or even more boldly "Thy humility." There is that in God which answers to the peculiarly human virtue of lowliness; and unless there were, man would remain small and unclothed with God-given strength. The devout soul thrills with wonder at God's stooping love, which it discerns to be the foundation of all His gifts and therefore of its blessedness. This singer saw deep into the heart of God, and anticipated the great word of the one Revealer, "I am meek and lowly in heart." But God's care for him does not merely fit him for the fight: it also orders circumstances so as to give him a free course. Having made his "feet like hinds' feet," God then prepares paths that he should walk in them. The work is only half done when the man is endowed for service or conflict; a field for his powers must be forthcoming, and God will take care that no strength given by Him lies idle for want of a wrestling ground. Sooner or later feet find the road.
Then follow six verses (37-42) full of the stir and tumult of battle. There is no necessity for the change to futures in the verbs of vv. 37, 38, which the R.V. adopts. The whole is a picture of past conflict, for which the psalmist had been equipped by God. It is a literal fight, the triumph of which still glows in the singer's heart and flames in his vivid words. We see him in swift pursuit, pressing hard on the enemy, crushing them with his fierce onset, trampling them under foot. They break and flee, shrieking out prayers, which the pursuer has a stern joy in knowing to be fruitless. His blows fall like those of a great pestle, and crush the fleeing wretches, who are scattered by his irresistible charge, like dust whirled by the storm. The last clause of the picture of the routed foe is better given by the various reading in 2 Samuel, which requires only a very slight alteration in one letter: "I did stamp them as the mire of the streets." Such delight in the enemy's despair and destruction, such gratification at hearing their vain cries to Jehovah, are far away from Christian sentiments; and the gulf is not wholly bridged by the consideration that the psalmist felt himself to be God's anointed, and enmity to him to be treason against God. Most natural as his feelings were, perfectly consistent with the level of religion proper to the then stage of revelation, capable of being purified into that triumph in the victory of good and ruin of evil without which there is no vigorous sympathy with Christ's battle, and kindling as they do by their splendid energy and condensed rapidity an answering glow in even readers so far away from their scene as we are, they are still of "another spirit" from that which Christ has breathed into the Church, and nothing but confusion and mischief can come of slurring over the difference. The light of battle which blazes in them is not the fire which Jesus longed to kindle upon earth.
Thus far the enemies seem to have been native foes rebelling against God's anointed or, if the reference to the Sauline persecution is held by, seeking to prevent his reaching his throne. But, in the concluding verses of this part (43-45), a transition is made to victory over "strangers," i.e. foreign nations. "The strivings of the people" seems to point back to the war described already, while "Thou hast made me the head of the nations" refers to external conquests. In 2 Samuel the reading is "my people," which would bring out the domestic reference more strongly; but the suffix for "my" may be a defective form of writing the plural; if so, the peoples in ver. 43 a are the "nations" of 43 b. In any case the royal singer celebrates the extension of his dominion. The tenses in vv. 44, 45, which the R.V. again gives as futures (as does Hupfeld), are better regarded, like all the others, as pasts. The wider dominion is not inconsistent with Davidic origin, as his conquests were extended beyond the territory of Israel. The picture of the hasty surrender of the enemy at the very sound of the conqueror's name is graphic. "They lied unto me," as the words in ver. 44 b are literally, gives forcibly the feigned submission covering bitter hate. "They fade away," as if withered by the simoom, the hot blast of the psalmist's conquering power. "They come trembling [or, as 2 Samuel reads, come limping] from their strongholds."
Vv. 46 to end make a noble close to a noble hymn, in which the singer's strong wing never flags nor the rush of thought and feeling slackens. Even more absolutely than in the rest of the psalm every victory is ascribed to Jehovah. He alone acts; the psalmist is simply the recipient. To have learned by life's struggles and deliverances that Jehovah is a living God and "my Rock" is to have gathered life's best fruit. A morning of tempest has cleared into sunny calm, as it always will, if tempest drives to God. He who cries to Jehovah when the floods of destruction make him afraid will in due time have to set to his seal that Jehovah liveth. If we begin with "The Lord is my Rock," we shall end with "Blessed be my Rock." Thankfulness does not weary of reiterating acknowledgments; and so the psalmist gathers up once more the main points of the psalm in these closing strains and lays all his mass of blessings at the feet of the Giver. His deliverance from his domestic foes and his conquests over external enemies are wholly God's work, and therefore supply both impulse and material for praises which shall sound out beyond the limits of Israel. The vow to give thanks among the nations has been thought fatal to the Davidic origin of the psalm. Seeing, however, that some foreign peoples were conquered by him, there was opportunity for its fulfilment. His function to make known the name of Jehovah was the reason for his victories. David had learned the purpose of his elevation, and recognised in an extended kingdom a wider audience for his song. Therefore Paul penetrates to the heart of the psalm when he quotes ver. 49 in Rom. xv. 9 as a proof that the evangelising of the Gentiles was an Old Testament hope. The plain lesson from the psalmist's vow is that God's mercies bind, and if felt aright will joyfully impel, the receiver to spread His name as far as his voice can reach. Love is sometimes silent, but gratitude must speak. The most unmusical voice is tuned to melody by thankfulness, and they need never want a theme who can tell what the Lord has done for their soul.
The last verse of the psalm is sometimes regarded as a liturgical addition, and the mention of David gratuitously supposed to be adverse to his authorship, but there is nothing unnatural in a king's mentioning himself in such a connection nor in the reference to his dynasty, which is evidently based upon the promise of perpetual dominion given through Nathan. The Christian reader knows how much more wonderful than the singer knew was the mercy granted to the king in that great promise, fulfilled in the Son of David, whose kingdom is an everlasting kingdom, and who bears God's name to all the nations.
