When mine enemies are turned back,.... As the Philistines were, when Goliath their champion was dead; and as the men that came to apprehend Christ, David's antitype, went backwards and fell to the ground, through the superior power of Christ; and as sin, Satan, and the world, and at last antichrist, are made to retreat from the Lord's people, who are more than conquerors over them through Christ that has loved them. "They shall fall and perish at thy presence"; they shall stumble at one thing or another which divine Providence will throw in their way to hinder them from executing their designs, and so fall before them they meant to destroy, and perish at the presence of God as wax melteth before the fire; see Psa 27:2; so antichrist shall be consumed with the breath of Christ's mouth, and the brightness of his coming, Th2 2:8; and this is the ground and foundation of the psalmist's joy, and rejoicing, and singing praise to God as it will be the reason of the joy of saints in the latter day, Rev 18:22. . Psalms 9:4 psa 9:4 psa 9:4 psa 9:4For thou hast maintained my right and my cause,.... Or vindicated and established his righteous cause; God had pleaded and defended it, and by the flight, fall, and ruin of his enemies, had clearly made it appear that his cause was just and good; thou sittest in the throne judging right; God has not only a throne of grace on which he sits, and from whence he distributes grace and mercy to his people, but he has a throne of judgment, and which is prepared for it, as in Psa 9:7; where he sits as the Judge of all the earth, and will do right; nor can he do otherwise, though his judgments are not always manifest in the present state of things; and the vindication of the psalmist's innocence and uprightness is another reason of his joy and gladness.
