Sirach 27:16

¹⁴The talk of him that sweareth much maketh the hair stand upright; and their brawls make one stop his ears.

¹⁵The strife of the proud is bloodshedding, and their revilings are grievous to the ear.

— Sirach 27:16 —

¹⁷Love thy friend, and be faithful unto him: but if thou betrayest his secrets, follow no more after him.

¹⁸For as a man hath destroyed his enemy; so hast thou lost the love of thy neighbor.
