Sirach 23:13
King James VersionSource notes
“Use not thy mouth to intemperate swearing, for therein is the word of sin.”
Context
10For as a servant that is continually beaten shall not be without a blue mark: so he that sweareth and nameth God continually shall not be faultless.
11A 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 offence: and if he swear in vain, he shall not be innocent, but his house shall be full of calamities.
12There 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.
13Use not thy mouth to intemperate swearing, for therein is the word of sin.
14Remember 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 they day of thy nativity.
15The man that is accustomed to opprobrious words will never be reformed all the days of his life.
16Two 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.
