Sirach 27:14-16

New Revised Standard Version, Anglicised

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.
