Wisdom of Ben Sira 13:16-18

New Catholic Bible

¹⁶ All creatures associate with their own kind,
    and every man sticks close to those like himself.
¹⁷ What does a wolf have in common with a lamb?
    The same applies to a sinner with a devout man.
¹⁸ What peaceful state can exist between a hyena and a dog?
    What peaceful condition can there be between the rich and the poor?^[a]
