Sirach 27:21-23

Good News Translation

²¹ Wounds can be bandaged and insults can be forgiven, but if you betray a confidence, it is hopeless.

Hypocrisy

²² When someone starts winking at you, he has something bad in mind, and nothing can stop him from going through with it. 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.
