19 Then your voice came to your holy one in a vision, saying, I have put the crown on a strong one, lifting up one taken from among the people. 20 I have made discovery of David my servant; I have put my holy oil on his head. 21 My hand will be his support; my arm will give him strength. 22 The deceit of those who are against him will not overcome him; he will not be troubled by the sons of evil. 23 I will have those who are against him broken before his face, and his haters will be crushed under my blows. 24 But my faith and my mercy will be with him; and in my name will his horn be lifted up. 25 I will put his hand in the sea, and his right hand in the rivers. 26 He will say to me, You are my father, my God, and the Rock of my salvation. 27 And I will make him the first of my sons, most high over the kings of the earth. 28 I will keep my mercy for him for ever; my agreement with him will not be changed. 29 His seed will keep their place for ever; his kingdom will be eternal, like the heavens. 30 If his children give up my law, and are not ruled by my decisions; 31 If my rules are broken, and my orders are not kept; 32 Then I will send punishment on them for their sin; my rod will be the reward of their evil-doing. 33 But I will not take away my mercy from him, and will not be false to my faith. 34 I will be true to my agreement; the things which have gone out of my lips will not be changed. 35 I have made an oath once by my holy name, that I will not be false to David. 36 His seed will not come to an end for ever; the seat of his kingdom will be like the sun before me. 37 It will be fixed for ever like the moon; and the witness in heaven is true. (Selah.)

Commentary on Psalm 89:19-37
(Read Psalm 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.
