But my faithfulness and my mercy shall be with him - I will at the same time be faithful to him, and merciful. These attributes of my nature shall be always attendant on him, as if they were his own.

And in my name - By me; or - He, acting in my name, and in my cause, shall be exalted.

Shall his horn be exalted - See the notes at Psalm 89:17.

But my faithfulness and my mercy shall be with him,.... The "faithfulness" of God was and is with Christ, in performing promises made to him respecting his work, and strength to do it, as man, and the glory that should follow; and also those made to his people in him, relating to grace here, and happiness hereafter: and though there was no "mercy" shown to Christ, as the surety of his people, but he was dealt with in strict justice; yet, as Mediator of the covenant, the special mercy of God is with him, even every blessing of it, called "the sure mercies of David"; and is only communicated through him; he is the mercy seat, from whence mercy is dispensed, and the propitiation through whom God is merciful to men; the words may be rendered, "my truth and my grace" (e), as they are by the Targum; and both are with Christ, the truth of doctrine, and all the fulness of grace, justifying, sanctifying, pardoning, adopting, and persevering grace, John 1:14,

and in my name shall his horn be exalted, or "his glory", as the Targum; his power and dominion, of which the horn is an emblem; and his glory is displayed in having the same name his Father has: his name is expressive of his nature, being, and perfections, the name Jehovah; and his name of title and office "King of Kings, and Lord of lords"; or his name the Word of God, as the Targum; who, as such, is the brightness of his Father's glory: or the sense is, that, by the power of God, he should be raised from the dead, and have glory given him, and be exalted at his right hand, and made Lord and Christ; or by means of the Gospel, which is the name of the Lord, John 17:6, his kingdom and dominion should be spread in the world; see 1 Samuel 2:10.

But my faithfulness and my {t} mercy shall be with him: and in my name shall his {u} horn be exalted.

(t) I will mercifully perform my promise to him despite his infirmities and offences.

(u) His power, glory and estate.

89:19-37 The Lord anointed David with the holy oil, not only as an emblem of the graces and gifts he received, but as a type of Christ, the King Priest, and Prophet, anointed with the Holy Ghost without measure. David after his anointing, was persecuted, but none could gain advantage against him. Yet all this was a faint shadow of the Redeemer's sufferings, deliverance, glory, and authority, in whom alone these predictions and promises are fully brought to pass. He is the mighty God. This is the Redeemer appointed for us, who alone is able to complete the work of our salvation. Let us seek an interest in these blessings, by the witness of the Holy Spirit in our hearts. As the Lord corrected the posterity of David for their transgressions, so his people shall be corrected for their sins. Yet it is but a rod, not a sword; it is to correct, not to destroy. It is a rod in the hand of God, who is wise, and knows what he does; gracious, and will do what is best. It is a rod which they shall never feel, but when there is need. As the sun and moon remain in heaven, whatever changes there seem to be in them, and again appear in due season; so the covenant of grace made in Christ, whatever alteration seems to come to it, should not be questioned.
