68:17 Chariots - The armies (whereof chariots were an eminent part in those times) which attend upon God to do his pleasure. Twenty thousand - An innumerable company, a certain number being put for an uncertain. Among them - Here the psalmist seems to be transported by the prophetic spirit, from the narration of those external successes, to the prediction of the Messiah; and of the transcendent privileges and blessings accruing to mankind thereby. As in Sinai - God is no less gloriously, though less terribly present here, than he was in Sinai, when the great God attended with thousands of his angels, solemnly appeared to deliver the law. Yea, here is a greater privilege than Sinai had, The Lord Jehovah descending from heaven into an human body, as appears by his ascending thither again, which the next verse describes.
68:15-21 The ascension of Christ must here be meant, and thereto it is applied, Eph 4:8. He received as the purchase of his death, the gifts needful for the conversion of sinners, and the salvation of believers. These he continually bestows, even on rebellious men, that the Lord God might dwell among them, as their Friend and Father. He gave gifts to men. Having received power to give eternal life, the Lord Jesus bestows it on as many as were given him, Joh 17:2. Christ came to a rebellious world, not to condemn it, but that through him it might be saved. The glory of Zion's King is, that he is a Saviour and Benefactor to all his willing people, and a consuming fire to all that persist in rebellion against him. So many, so weighty are the gifts of God's bounty, that he may be truly said to load us with them. He will not put us off with present things for a portion, but will be the God of our salvation. The Lord Jesus has authority and power to rescue his people from the dominion of death, by taking away the sting of it from them when they die, and giving them complete victory over it when they rise again. The crown of the head, the chief pride and glory of the enemy, shall be smitten; Christ shall crush the head of the serpent.
