Matthew Henry on Psalms 76:1-6

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