Bible reading for my ex-friends

Sirach 27: 16-21

He who betrays a secret cannot be trusted,
he will never find an intimate friend.
Cherish your friend, keep faith with him;
but if you betray his confidence, follow him not;
For as an enemy might kill a man,
you have killed your neighbor's friendship.

Like a bird released from the hand,
you have let your friend go and cannot recapture him;
Follow him not, for he is far away,
he has fled like a gazelle from the trap.
A wound can be bound up, and an insult
forgiven,
But he who betrays secrets does hopeless damage.
