Matthew Henry's Complete Bible Commentary
Verse 63
David had often expressed the great love he had to God; here he expresses the great love he had to the people of God; and observe, 1. Why he loved them; not so much because they were his best friends, most firm to his interest and most forward to serve him, but because they were such as feared God and kept his precepts, and so did him honour and helped to support his kingdom among men. Our love to the saints is then sincere when we love them for the sake of what we see of God in them and the service they do to him. 2. How he showed his love to them: He was a companion of them. He had not only a spiritual communion with them in the same faith and hope, but he joined with them in holy ordinances in the courts of the Lord, where rich and poor, prince and peasant, meet together. He sympathized with them in their joys and sorrows (Hebrews 10:33); he conversed familiarly with them, communicated his experiences to them, and consulted theirs. He not only took such to be his companions as did fear God, but he vouchsafed himself to be a companion with all, with any, that did so, wherever he met with them. Though he was a king, he would associate with the poorest of his subjects that feared God, Psalms 15:4, 2:1. MHBCC 598.56
