that they may know that you alone, whose name is the LORD, are the Most High over all the earth.
PSALM 83 The prophet implores the divine aid against the enemies of the Church, and, as an argument for obtaining this the more easily, he enumerates the many nations which had conspired together for the express purpose of exterminating the people of Israel, and thereby extinguishing the very name of the Church of God.
Commenting on Psalm 83:1-18
That men may know that thou, whose name alone is Jehovah, art the most high over all the earth. Hearing of the Lord's marvellous deeds in defeating such a numerous confederacy, the very heathen would be compelled to acknowledge the greatness of Jehovah. We read in 2Ch 20:30, that the fear of God was on all the neighbouring kingdoms when they heard that Jehovah fought against the enemies of Israel.
The psalmist here, in the name of the church, prays for the destruction of those confederate forces, and, in God's name, foretels it; for this prayer that it might be so amounts to a prophecy that it shall be so, and this prophecy reaches to all the enemies of the gospel-church; whoever they be that oppose the kingdom of Christ, here they may read their doom.
