John Gill's Exposition of the Whole Bible
Psalms 94:1
O Lord God, to whom vengeance belongeth,.... As it does to God, and to him only; not to Heathen deities, one of which has the name of Vengeance given it, Acts 28:4, nor to Satan, the enemy and avenger, and his spiteful principalities and powers; nor to men, who are not to exercise private revenge on their fellow creatures; only to civil magistrates, to whom public revenge belongs, they being God's viceregents, and representing him; otherwise to God only it belongs, against whom sin is committed; and he will, in his own time and way, execute it; he is "the God of revenges" e, as the words may be rendered; and this is applicable to Christ, who is the true Jehovah, and God over all: it was he that took vengeance on Sodom and Gomorrah, and rained from the Lord fire and brimstone on them; and who took vengeance on the inventions of the Israelites in the wilderness; and when he came in the flesh, he came with vengeance to destroy Satan and his works, as it was promised and prophesied he should, Isaiah 35:4, forty years after his death, resurrection, and ascension, he came in his power and kingdom, and took vengeance on the Jewish nation, for their unbelief and rejection of him, Luke 21:22, and at the opening of the sixth seal his wrath came upon Rome Pagan in a manner intolerable to them, for their cruel persecutions of his church and people; and the cry of the souls under the altar was much like what is uttered in this psalm; see Revelation 6:9, and at the time of his spiritual coming and reign he will avenge the blood of his saints on Rome Papal, or antichrist, whom he will destroy with the breath of his mouth, and the saints will be called upon to rejoice, and will rejoice, when they see the vengeance, Revelation 18:20 and his personal coming will be in flaming fire, to take vengeance on them that know not God, and obey not his Gospel, and when all the wicked will suffer the vengeance of eternal fire, 2 Thessalonians 1:8.
O God, to whom vengeance belongeth; which is repeated to observe the certainty of it, and to express the vehement and importunate desire of the psalmist, and those he represents, that he would show himself to be so, follows:
show thyself; or "shine forth" f, as in Psalms 80:1 either at his incarnation, when he appeared as the dayspring from on high; yea, as the sun of righteousness; or, in the ministry of the Gospel, the great light which shone first on the inhabitants of Judea and Galilee, and then on the Gentile world; or in his gracious presence with his people, which is expressed by causing his face to shine upon them, Psalms 80:7, or in the protection of them, and destruction of their enemies; which is a showing himself strong on their behalf, an appearing to the joy of the one, and the confusion of the other; and in this manner will Christ show himself in the latter day.
