Psalms 109:5

5 But I gave myself to prayer Some are of opinion, that these words refer to David’s pouring out a prayer for his enemies at the very moment when they were furiously assaulting him, and with this opinion corresponds that which we have stated in Psalm 35:13. But the more plain, and, to me, the preferable interpretation, is, that when he was attacked in a cruel and hostile manner, he did not betake himself to such unlawful means as the rendering of evil for evil, but committed himself into the hand of God, fully satisfied that he alone could guard him from all ill. And it is assuredly a great and desirable attainment for a man so to restrain his passions as directly and immediately to make his appeal to God’s tribunal, at the very time when he is abused without a cause, and when the very injuries which he sustains are calculated to excite him to avenge them. For there are some persons who, while it is their aim to live in terms of friendship with the good, coming in contact with ill men, imagine that they are at perfect liberty to return injury for injury; and to this temptation all the godly feel that they are liable. The Holy Spirit, however, restrains us, so that though oftimes provoked by the cruelty of our enemies to seek revenge, we yet abandon all fraudulent and violent means, and betake ourselves by prayer to God alone. By this example, which David here sets before us, we are instructed that we must have recourse to the same means if we would wish to overcome our enemies through the power and protection of God. In Psalm 69:13, we have a parallel passage: “They that sit in the gate spake against me; and I was the song of those who drink strong drink. But my prayer was made to thee, O Jehovah!” In that passage, as well as in the one under review, the mode of expression is elliptical. Besides, it is the design of David in these words to inform us, that although he was aware that the whole world was opposed to him, yet he could cast all his cares upon God, and this was enough to render his mind calm and composed. And as the Holy Spirit taught David and all the godly to offer up prayers like these, it must follow, that those who, in this respect, imitate them, will be promptly helped by God when he beholds them reproachfully and vilely persecuted.
