John Chrysostom, on Ps 103:20

“Thou hast appointed darkness, and it is night: in it shall all the beasts of the woods go about:”

“Then, even if anger boils up, it is easily cooled. If passion flares forth, the flames are readily quenched. If envy consumes us, it is not difficult to drive it away. The same thing happens that the prophet says happens when the sun rises. What did he say? "You made the darkness, and it was night. In it all the wild beasts of the forest will go forth, even young lions roaring for prey and to seek meat for themselves from God. The sun arose, and they were gathered together and shall lie down in their dens." At sunrise, then, every wild beast is driven off and slinks away to its lair. So, too, when a prayer, like a ray of the sun, arises from our tongue and comes forth from our mouth, our mind is enlightened, all the savage passions that destroy our reason slink away and flee to their own lairs, if only our prayer is diligent, if only it comes from a watchful soul and sober mind. Should the devil be on hand when we pray, he is driven off; should a demon be there, he slinks away.”
