John Chrysostom — on Ps 9:6 (COMMENTARY ON THE PSALMS 9:3)

“God's anger is like that, you see: it razes and destroys everything. Or what another translator teaches us in saying "deserts," implying that he razed not only their inhabited places but also their uninhabited places, and laid waste their cities. Such, in fact, is the way the righteous person waged war, such the way he put down his foes, not employing light and heavy weapons but enjoying grace from God. Hence for him the war was glorious and famous, and his victory overwhelming.”
