Charles H. Spurgeon on Psalms 76:9

God arose to judgment. This great judgment was wrought upon the enemies when God rose: it was not done when God sat; for the whole time when he sat his enemies were aloft, stirring their time, raging in murder, oppression, and blood... He bringeth in God here after the manner of earthly judges, after the custom of our judges; for first they sit down, they try, seek out, and advise, and after consideration they resolve, and after resolution they rise up, give forth judgment, and pronounce the sentence; even so the prophet bringeth in God after the same manner; sitting, and after sitting, rising and pronouncing the sentence. Robert Bruce.
