Now the Lord of peace himself,.... The Prince of peace, who is peaceable himself, and the author of peace in all his churches, and who requires peace, calls for it, and encourages it:give you peace always by all means; both a conscience peace, through the blood, righteousness, and sacrifice of Christ, and faith in them, which passes all understanding, and which, when he gives, none can take away; and a church peace, being freed from all such disorderly persons and their abettors, the disturbers of it: and indeed, the way to have true peace and prosperity in churches is to keep up the discipline of God's house.
The apostle prays for it in faith, upon an observance of the rules he had given; he prays for constant and perpetual peace, which is greatly to be desired; and that it might be had by all means, and in every way through praying, preaching, administering the ordinances, laying on censures, when necessary, and Christian conversation.
Some copies, and the Vulgate Latin version, read "in every place"; as well as at Thessalonica.
