Verse 28. - My mercy will I keep for him for evermore (comp. 2 Samuel 7:15, "My mercy shall not depart away from him"). And my covenant shall stand fast with him (see 2 Samuel 7:16; 2 Samuel 23:5).
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.
My mercy will I keep for him for evermore,.... That is, for his mystical body, his church and people; for whom stores of mercy are kept with him, to be laid out in their regeneration, pardon, salvation, and eternal life; for to them the mercy of God is from everlasting to everlasting, Psalm 103:17, unless this is to be understood of the "grace" and "kindness" (g) of God, as the word may be rendered; his free favour and love to Christ, which always continues; for as he was always his dearly beloved Son, that lay in his bosom from eternity, so he continued, throughout his state, of humiliation, his well beloved, in whom he was well pleased, and still is, and ever will:
and my covenant shall stand fast with him; being made with him as the head and representative of his people, it remains, and will remain, sure, firm, and immoveable; its blessings are "sure mercies", and its promises are all "yea and amen in Christ": the stability of it, and of all that is in it, is owing to its being made with him, and being in his hands, who is the surety, Mediator, and messenger of it.
