Ben Sira 27:25

25 Whoever throws a stone straight up throws it on his own head; and a treacherous blow opens up wounds.

Ben Sira 27:25 In-Context

23 In your presence his mouth is all sweetness, and he admires your words; but later he will twist his speech and with your own words he will give offense.
24 I have hated many things, but none to be compared to him; even the Lord will hate him.
25 Whoever throws a stone straight up throws it on his own head; and a treacherous blow opens up wounds.
26 He who digs a pit will fall into it, and he who sets a snare will be caught in it.
27 If a man does evil, it will roll back upon him, and he will not know where it came from.
