Now viewing scripture range from the book of Ecclesiasticus chapter 23:10 through chapter 23:13...
10 For 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.
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 offence: 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 Use not thy mouth to intemperate swearing, for therein is the word of sin.
