Ben Sira 27:11-21

11 The conversation of the godly is always wise, but the fool changes like the moon.
12 Among stupid people limit your time, but among thoughtful people linger on.
13 The talk of fools is offensive, and their laughter is wantonly sinful.
14 Their cursing and swearing make one's hair stand on end, and their quarrels make others stop their ears.
15 The strife of the proud leads to bloodshed, and their abuse is grievous to hear.
16 Whoever betrays secrets destroys confidence, and will never find a congenial friend.
17 Love your friend and keep faith with him; but if you betray his secrets, do not follow after him.
18 For as a person 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.
