Now viewing scripture range from the book of Ecclesiasticus chapter 23:9 through chapter 23:12...
9 Accustom not thy mouth to swearing; neither use thyself to the naming of the Holy One.
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.
