Charles H. Spurgeon on Psalms 7:1

Title. "Shiggaion," though some have attempted to fix on it a reference to the moral aspect of the world as depicted in this Psalm, is in all probability to be taken as expressing the nature of the composition. It conveys the idea of something erratic ((Heb.), to wander) in the style; something not so calm as other Psalms; and hence Ewald suggests, that it might be rendered, "a confused ode," a Dithyramb. This characteristic of excitement in the style, and a kind of disorder in the sense, suits Habakkuk 3:1, the only other place where the word occurs. Andrew A. Bonar. Whole Psalm. Whatever might be the occasion of the Psalm, the real subject seems to be the Messiah's appeal to God against the false accusations of his enemies; and the predictions which it contains of the final conversion of the whole world, and of the future judgment, are clear and explicit. Samuel Horsley, LL.D., 1733-1806.

"O Lord, my God, in thee do I put my trust." This is the first instance in the Psalms where David addresses the Almighty by the united names Jehovah and my God. No more suitable words can be placed at the beginning of any act of prayer or praise. These names show the ground of the confidence afterward expressed. They "denote at once supreme reverence and the most endearing confidence. They convey a recognition of God's infinite perfections, and of his covenanted and gracious relations." William S. Plumer.
