Charles H. Spurgeon on Psalms 83:2

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.
