Sirach 27:13-15

Revised Standard Version

¹³ The talk of fools is offensive,
    and their laughter is wantonly sinful.
¹⁴ The talk of men given to swearing makes one’s hair stand on end,
    and their quarrels make a man stop his ears.
¹⁵ The strife of the proud leads to bloodshed,
    and their abuse is grievous to hear.
