Ben Sira 27:18-28

18 For as a man destroys his enemy, so you have destroyed the friendship of your neighbor.
19 And as you allow a bird to escape from your hand, so you have let your neighbor go, and will not catch him again.
20 Do not go after him, for he is too far off, and has escaped like a gazelle from a snare.
21 For a wound may be bandaged, and there is reconciliation after abuse, but whoever has betrayed secrets is without hope.
22 Whoever winks his eye plans evil deeds, and no one can keep him from them.
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.
28 Mockery and abuse issue from the proud man, but vengeance lies in wait for him like a lion.
