| Matthew Henry's Concise Commentary 109:1-5. It is the unspeakable comfort of all believers, that whoever is against them, God is for them; and to him they may apply as to one pleased to concern himself for them. David's enemies laughed at him for his devotion, but they could not laugh him out of it.
Pulpit CommentaryVerse 4. - For my love they are my adversaries. The tenderness and kindness of the good towards wicked men does not soften them. Rather it provokes them to greater hostility. This was seen clearly in the instance of Saul. But I give myself unto prayer; literally, but I prayer; i.e. "but I am wholly prayer," "I do nothing during their attacks on me but pray for them."
Gill's Exposition of the Entire BibleFor my love they are my adversaries,.... For the love that Christ showed to the Jews; to their bodies, in going about and healing all manner of diseases among them; to their souls, in preaching, the Gospel to them in each of their cities; and for the love he showed to mankind in coming into the world to save them, which should have commanded love again; but instead of this they became his implacable adversaries: they acted the part of Satan; they were as so many Satans to him, as the word signifies. But I give myself unto prayer; or "I am a man of prayer" (y); as Aben Ezra and Kimchi supply it; so he was in the days of his flesh, Hebrews 5:7, he was constant at it, and fervent in it; sometimes a whole night together at it: his usual method was, when at Jerusalem, to teach in the temple in the daytime, and at night to go to the mount of Olives, and there abide and pray, Luke 6:12. This was the armour he alone made use of against his enemies, when they fought against him, and acted the part of an adversary to him; he betook himself to nothing else but prayer; he did not return railing for railing, but committed himself in prayer to God, who judgeth righteously, 1 Peter 2:23, yea, he prayed for those his adversaries: and so Aben Ezra and Kimchi interpret it, that he was a man of prayer for them, and prayed for them; as it is certain Christ did, when he was encompassed by his enemies, and they were venting all their spite and malice against him, Luke 23:34. (y) "et ego vir orationis", Pagninus, Gejerus.
Jamieson-Fausset-Brown Bible Commentary4, 5. They return evil for good (compare Ps 27:12; Pr 17:13). I give myself unto prayer—or literally, "I (am) prayer," or, "as for me, prayer," that is, it is my resource for comfort in distress.
