Albert Barnes Commentary Psalms 92:4

"For thou, Jehovah, hast made me glad through thy work: I will triumph in the works of thy hands." — Psalms 92:4 (ASV)

For you, Lord, have made me glad—You have made me happy; you have given me such a state of feeling as finds an appropriate expression in “praise.”

Through your work—This refers to either the work of creation, the finishing of which the Sabbath was designed particularly to commemorate; or the works of God in general—the universe; or the general dealings of his providence; or some particular interpositions of Providence on his behalf that called for special praise.

All these are appropriately combined in the celebrations—the praises—of the Sabbath.

To these should be added, as among the most marvelous of his works, and that which furnishes special occasion for praise on the Christian Sabbath, the wonderful work of redemption—that which of all the “works” of God makes a heart rightly affected most “glad.”

I will triumph—I will exult or rejoice.

In the works of your hands—In all your works; in all that you have done.
