Sirach 12:13-15

New Revised Standard Version, Anglicised Catholic Edition

¹³ Who pities a snake-charmer when he is bitten,
    or all those who go near wild animals?
¹⁴ So no one pities a person who associates with a sinner
    and becomes involved in the other’s sins.
¹⁵ He stands by you for a while,
    but if you falter, he will not be there.
