Wisdom of Ben Sira 27:15-17

New Catholic Bible

¹⁵ The arguments among the arrogant lead to bloodshed;
    their abuse is painful to listen to.

¹⁶ Anyone who betrays secrets forfeits any right to trust,
    and he will never find a close friend.
¹⁷ Love your friend and keep faith with him,
    but if you betray his secrets, do not attempt to remain by his side.
