Wisdom of Ben Sira 12:13-15

New Catholic Bible

¹³ Who has sympathy for a snake charmer when he is bitten,
    or for those who go near wild animals?
¹⁴ In the same way, no one pities a person who associates with sinners
    and becomes involved in their evil deeds.
¹⁵ He may stand by you for a while,
    but if you falter, he will not stay around.
