Psalms 68:28

28. Thy God hath commanded thy strength Men are always disposed to arrogate to themselves the glory of what they may have done instead of tracing their success to God, and David reminds the people once more that they had not triumphed by their own strength, but by power communicated from above. If they had acquitted themselves with energy on the field, he would have them consider that it was God who inspired them with this valor, and would guard them against the pride which overlooks and disparages the Divine goodness. As a consideration which might farther tend to promote humility in their minds, he adverts to the dependence in which they stood of the future continuance of the same favor and protection; this being the great cause of presumptuous confidence, that we do not feel our own helplessness, and are not led under a sense of it to resort humbly to God for the supply of our wants. Another lesson which the passage teaches us is, that more is required than that God should visit us at first with his preventing grace; that we stand constantly in need of his assistance throughout our whole lives. If this be true in the literal warfare, where our conflict is with flesh and blood, it must be still more so in matters of the soul. It is impossible that we could stand one moment in the contest with such enemies as Satan, sin, and the world, did we not receive from God the grace which secures our perseverance.

What is said of the temple in the following verse is intended to carry out the same strain of sentiment which has been already expressed. It gives the reason why God had exerted his power in behalf of the Israelites rather than others; which was, that it might be displayed as coming forth from the sanctuary and the ark of the covenant. Hence the emphasis with which David calls him in a previous part of the psalm — the God of Israel. It was not in vain that God had erected his sanctuary, or promised his presence in connection with it; and his power is here represented as issuing from the temple, to denote that the only security for his favor was to be found in his gracious covenant and promises. Some read, From thy temple in Jerusalem — a frigid interpretation, and one which does not express the meaning of the Psalmist. His prayer is to the effect that the Divine power might be commanded from the sanctuary upon his chosen people, here denoted by a common figure of speech by Jerusalem. It may be asked how he speaks of the temple, when it had not been yet built. The word temple or palace may have been used to express the tabernacle. This, at least, I think more probable than that he should speak of the temple by anticipation, as some suppose; and there can be no doubt that the ark had already been placed in Zion. Having already traced all the honor of the recent victories to God, he next proceeds to vindicate his claim to reap the fruits of them, by asserting that the kings who had been subdued would acknowledge God to have been their conqueror, as well as yield themselves tributary to David and his successors, — a circumstance which should lay the people of God under an additional obligation to present him with their free-will offerings of praise.
