Do to them as you did to Midian, as to Sisera and Jabin at the river Kishon,
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
Do unto them as unto the Midianites. Faith delights to light upon precedents, and quote them before the Lord; in the present instance, Asaph found a very appropriate one, for the nations in both cases were very much the same, and the plight of the Israelites very similar.
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.
