89:3 {d} I have made a covenant with my chosen, I have sworn unto David my servant,
(d) The prophet shows what the promise of God was, on which he grounded his faith.
89:3 Chosen - With David; whom I have chosen to the kingdom.
89:1-4 Though our expectations may be disappointed, yet God's promises are established in the heavens, in his eternal counsels; they are out of the reach of opposers in hell and earth. And faith in the boundless mercy and everlasting truth of God, may bring comfort even in the deepest trials.
