Psalms 36:9 - Joseph Benson’s Commentary on the Old and New Testaments

With thee is the fountain of life From which those rivers of pleasure flow. Life is in God as in a fountain, and from him is derived to us. As the God of nature, he is the fountain of natural life; in him we live, and move, and have our being. As the God of grace, he is the fountain of spiritual life: all the strength and comfort of sanctified souls; all their gracious principles, powers, and performances, are from him. He is the spring and author of all their sensations of divine things, and of all their motions toward them; and he invites all that thirst, nay, and whosoever will, to come and partake of these waters of life freely. As the God of glory, he is the fountain of eternal life: the happiness of glorified saints consists in the vision and fruition of him, and in the immediate communications of his love, without interruption, or fear, or cessation. This glorious, blessed, and endless life is alone worthy of the name of life: this present temporal life being only a passage to death, and a theatre of great and manifold calamities. In thy light In the knowledge of thee in grace, and the vision of thee in glory; especially in the latter; in the light of thy countenance, or glorious presence, which then shall be fully manifested unto us, when we shall see thee clearly and face to face, and not through a glass and darkly, as we now see; shall we see light The light of life, as it is called, John 8:12; light in this clause being the same thing with life in the former: pure light without any mixture of darkness; knowledge without ignorance, holiness without sin, happiness without misery. The word light is elegantly repeated in another signification; in the former clause it is light discovering, in this, light discovered or enjoyed.
