Musar do Sofoniasza 3:3

And just as God, Blessed be He, made some birds, fish and animals that are too tame and loving to plunder one another, and others that are cruel and prey upon and swallow one another, so also did he make men. The good men may be compared to the good birds and cattle as it is said, "My dove, my undefiled" (Cant. 5:2). And it is said, "And ye are My sheep of My pasture" (Ezek. 34:31). And evil men may be compared to evil beasts. To a lion, as it is written, "He is like a lion that is eager to tear in pieces" (Ps. 17:12). And some are like bears and wolves, as it is said, "Her judges are wolves of the desert" (Zeph. 3:3).
