John Calvin Commentary Psalms 76:1

"In Judah is God known: His name is great in Israel." — Psalms 76:1 (ASV)

God is known in Judah. At the beginning, we are taught that it was not by human means that the enemies of Israel were forced to retreat without achieving anything, but by the ever-to-be-remembered aid of Jehovah. From where did that knowledge of God and the greatness of his name which are spoken of come, if not because He stretched out his hand in an extraordinary way, to make it clearly evident that both the chosen people and the city were under his defense and protection? It is therefore asserted that the glory of God was conspicuously displayed when the enemies of Israel were defeated by such a miraculous intervention.
