His seed shall endure forever ... - His posterity. See the notes at Psalm 89:29. There, the expression is, "his throne as the days of heaven." Here it is, "his throne as the sun before me." The meaning is the same. It would stand through all time. Compare the notes at Psalm 72:5.

His throne as the son - Splendid and glorious! dispensing light, heat, life, and salvation to all mankind.

His seed shall endure for ever,.... This is a confirmation by his oath of what he had before said, Psalm 89:29 which may be understood either of the perseverance of particular believers, of everyone of the spiritual seed of Christ; or of the duration of the church in general, throughout all ages, as before observed; and these being matters of moment and importance, and of which there are sometimes doubts in the minds of the Lord's people about them, and that they may be firmly believed by them, he confirms them with an oath; for God never swears to trivial things; and when he does swear, it is to remove the doubts of his people, and make their minds easy:

and his throne as the sun before me; that is, shall continue as long as it does; see Psalm 89:29, or shall be bright, splendid, and glorious as the sun, so the Targum,

"and his throne light as the sun before me;''

meaning his church and kingdom, of which the throne is an emblem, and which became so in Gospel times, clear and lucid as the sun, Sol 6:10, when day was made by the rising of the sun of righteousness, and by the bright shining of the Gospel ministry; and at particular periods since, as in the times of Constantine, when the church was clothed with the sun, and at the Reformation, when Christ appeared with a rainbow on his head, and his face was as the sun, Revelation 12:1 and especially this will be the case of the church in the latter day, when the light of the moon will be as the light of the sun, and the light of the sun seven fold, as the light of seven days; and when the city, the church, will stand in no need of the sun, nor of the moon; and also in the ultimate glory, when the saints will shine as the sun in the kingdom of God; see Isaiah 30:26. This passage is applied to the Messiah by the Jews (a).

(a) Zohar in Gen. fol. 30. 1.

His seed shall endure for ever, and his throne as the sun before me.

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.
