Sirach 13:15-17

New Revised Standard Version, Anglicised Catholic Edition

¹⁵ Every creature loves its like,
    and every person a neighbour.
¹⁶ All living beings associate with their own kind,
    and people stick close to those like themselves.
¹⁷ What does a wolf have in common with a lamb?
    No more has a sinner with the devout.
