Matthew Henry Commentary Psalms 76:1-6

"In Judah is God known: His name is great in Israel. In Salem also is his tabernacle, And his dwelling-place in Zion. There he brake the arrows of the bow; The shield, and the sword, and the battle. Selah Glorious art thou [and] excellent, From the mountains of prey. The stouthearted are made a spoil, They have slept their sleep; And none of the men of might have found their hands. At thy rebuke, O God of Jacob, Both chariot and horse are cast into a deep sleep." — Psalms 76:1-6 (ASV)

Happy people are those who have their land filled with the knowledge of God! Happy persons who have their hearts filled with that knowledge! It is the glory and happiness of a people to have God among them by His ordinances. Where the enemies of the church act proudly, it will appear that God is above them. See the power of God's rebukes. Christians may with pleasure apply this to the advantages bestowed by the Redeemer.
