This psalm calls more for devotion than exposition; it is a most excellent psalm of praise, and of general use. The psalmist, I. Stirs up himself and his own soul to praise God (Psalms 102:1, 102:2) for his favour to him in particular (Psalms 102:3-102:5), to the church in general, and to all good men, to whom he is, and will be, just, and kind, and constant (Psalms 102:6-102:18), and for his government of the world, Psalms 102:19. II. He desires the assistance of the holy angels, and all the works of God, in praising him, Psalms 102:20-102:22. In singing this psalm we must in a special manner get our hearts affected with the goodness of God and enlarged in love and thankfulness. MHBCC 582.1
