Ben Sira 27:25

25 Throw a stone straight up in the air and it will come down on your head. Strike a blow, and you yourself will be wounded.

Ben Sira 27:25 In-Context

23 When he's with you, his talk is so nice! He compliments you on every word you say. But behind your back it's a different story; he will take what you have said and turn it against you.

24 There is nothing in the world that I hate as much as a person like that - and the Lord hates him too.

25 Throw a stone straight up in the air and it will come down on your head. Strike a blow, and you yourself will be wounded.

26 People who set traps fall into them themselves.

27 People who hurt others will be hurt by their own actions and will have no idea why.
