Psalms 68:3

But let the righteous be glad,.... At the incarnation of Christ, which is matter of joy to all people that believe in him; as did Zacharias and Elisabeth, who were both righteous, and also Simeon; and at his resurrection from the dead, since it is for their justification, by which they are denominated righteous; as did the disciples of Christ, and as do saints in all ages; who know the power of his resurrection, and the influence it has on the regeneration of their souls, the justification of their persons now, and the resurrection of their bodies hereafter; and at the destruction of the enemies of Christ and theirs;

let them rejoice before God; in the presence of him; enjoying communion with him; having views of interest in him; as they do when this is the case, and as they will when they shall appear before him, and stand at his right hand at the last day, clothed with his righteousness, and having palms in their hands;

yea, let them exceedingly rejoice; as they have just reason to do, in his person, grace, righteousness, and salvation. All these expressions denote the greatness, frequency, fervency, fulness, and continuance of their joy. They may be rendered in the future, "but the righteous shall be glad" p, c. so the Targum.
