Charles H. Spurgeon on Psalms 2:1

"Why do nations make a noise," tumultuate, or rage? The Hebrew verb is not expressive of an internal feeling, but of the outward agitation which denotes it. There may be an allusion to the rolling and roaring of the sea, often used as an emblem of popular commotion, both in the Scriptures and the classics. The past tense of this verb (Why have they raged?) refers to the commotion as already begun, while the future in the next clause expresses its continuance. J. A. Alexander, D.D., 1850.
