Wisdom of Ben Sira 27:23-25

New Catholic Bible

²³ He speaks sweetly while in your presence,
    and admires your every word,
but later he will change his tune,
    and with your own words he will trip you up.
²⁴ I have found many things to hate, but nothing so much as this man,
    and the Lord despises him too.
²⁵ Whoever throws a stone straight up into the air will see it descend on his own head,
    and a treacherous blow will cut both ways.
