I have made a covenant with my chosen - With my chosen one; that is, with David. The original is in the singular number, though by the Septuagint, and the Vulgate, and by Luther, it is rendered in the plural - chosen ones - elect. This is undoubtedly the language of God himself, though it is not expressly ascribed to him. The design is to describe the solemn promise which God had made to David and to his posterity. Compare Psalm 78:70-71. See also, on the use of the phrase "made a covenant," see Psalm 50:5, note; Psalm 83:5, note.

I have sworn unto David my servant - I have taken a solemn oath in regard to him. The substance of the oath is stated in the next verse. The promise referred to is found in 2 Samuel 7:11-16.

I have made a covenant with my chosen - I have made a covenant with Abraham, Isaac, and Jacob; and renewed it with Moses and Joshua in reference to the Israelites in general: but I have made one with David in especial relation to himself and posterity, of whom, according to the flesh, the Christ is to come. And this is the covenant with David: -

I have made a covenant with my chosen,.... Not with Abraham, as the Targum expresses it: but with David, as in the following clause; not David, literally understood, though he was chosen of the Lord to be his servant, and a covenant was made with him, and a promise made to him of the perpetuity of his throne and kingdom in his family, Psalm 78:70 but mystical David, the Messiah, David's son and antitype; after, on this account, called David in Scripture, Ezekiel 34:23 and who is the Lord's "chosen" One, foreordained to be the Redeemer of lost sinners, chosen to be the Mediator between God and them, to be the head of the church, and Saviour of the body; and his human nature was chosen to the grace of union to the Son of God, Psalm 89:19, hence he is called God's elect, Isaiah 43:1 and with him the covenant of grace was made from all eternity, and all the blessings and promises of it were put into his hands; he is the Mediator, surety, and messenger of it, and by his blood it is ratified and confirmed: the Septuagint render it, in the plural number, "with mine elect ones"; and it is a truth, that the covenant of grace is made with all the elect, considered in Christ, and is made with them as such, and not as believers, converted persons, &c. election is the foundation of the covenant, and the source of all covenant blessings:

I have sworn unto David my servant: to the Messiah, called David, as before observed, and who is the Lord's servant, as man and Mediator, of his choosing, calling, sending, and supporting, Isaiah 42:1, to whom he swore, and he will not repent; and which oath of his, joined to his covenant and promise, makes for the strong consolation of the heirs of promise; see Psalm 89:35, the sum and substance of which covenant and oath follow.

{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.

3, 4. The object of this faith expressed in God's words (2Sa 7:11-16).

with-or literally, "to"

my chosen-as the covenant is in the form of a promise.

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.
