Psalms 83:2

Sometimes God seems not to be concerned at the unjust treatment of his people. But then we may call upon him, as the psalmist here. All wicked people are God's enemies, especially wicked persecutors. The Lord's people are his hidden one; the world knows them not. He takes them under his special protection. Do the enemies of the church act with one consent to destroy it, and shall not the friends of the church be united? Wicked men wish that there might be no religion among mankind. They would gladly see all its restraints shaken off, and all that preach, profess, or practise it, cut off. This they would bring to pass if it were in their power. The enemies of God's church have always been many: this magnifies the power of the Lord in preserving to himself a church in the world.

For, lo, thine enemies make a tumult. They are by no means sparing of their words, they are like a hungry pack of dogs, all giving tongue at once. So sure are they of devouring thy people that they already shout over the feast. And they that hate thee have lifted up the head. Confident of conquest, they carry themselves proudly and exalt themselves as if their anticipated victories were already obtained. These enemies of Israel were also God's enemies, and are here described as such by way of adding intensity to the argument of the intercession. The adversaries of the church are usually a noisy and a boastful crew. Their pride is a brass which always sounds, a cymbal which is ever tinkling.
