Ben Sira 23:13

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

Ben Sira 23:13 In-Context

11 A man that useth much swearing shall be filled with iniquity, and the plague shall never depart from his house. If he shall offend, his sin shall be upon him; and if he acknowledge not his sin, he maketh a double offense; and if he swear in vain, he shall not be innocent, but his house shall be full of calamities.

12 There is a word that is clothed about with death; God grant that it be not found in the heritage of Jacob! For all such things shall be far from the godly, and they shall not wallow in their sins.

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.
