Ben Sira 23:15

15 The man that is accustomed to opprobrious words will never be reformed all the days of his life.

Ben Sira 23:15 In-Context

13 Accustom not thy mouth to intemperate swearing, for therein is the word of sin.

14 Remember thy father and thy mother when thou sittest among great men. Be not forgetful before them, and so thou by thy custom become a fool, and wish that thou hadst not been born, and curse the day of thy nativity

15 The man that is accustomed to opprobrious words will never be reformed all the days of his life.

16 Two sorts of men multiply sin, and the third will bring wrath: a hot mind is as a burning fire, it will never be quenched till it be consumed; a fornicator in the body of his flesh will never cease till he hath kindled a fire.

17 All bread is sweet to a whoremonger; he will not leave off till he die.
