Sirach 27:13-15

New Revised Standard Version Catholic Edition

¹³ The talk of fools is offensive,
    and their laughter is wantonly sinful.
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.
