Sirach 27:13

13 The discourse of fools is irksome, and their sport is the wantonness of sin.

Sirach 27:13 In-Context

11 The discourse of a godly man is always with wisdom; but a fool changeth as the moon.
12 If thou be among the indiscreet, observe the time; but be continually among men of understanding.
13 The discourse of fools is irksome, and their sport is the wantonness of sin.
14 The talk of him that sweareth much maketh the hair stand upright; and their brawls make one stop his ears.
15 The strife of the proud is bloodshedding, and their revilings are grievous to the ear.
