Sirach 28:12 In-Context

10 A fire burns in proportion to its fuel, and conflict increases the longer it continues. The more powerful individuals are, the stronger their anger will be; and the wealthier they are, the more their wrath will increase.

11 A hasty quarrel sparks a fire, and hasty conflict sheds blood.

12 If you blow on a spark, it will flame up, and if you spit on it, it will go out; nonetheless, both come out of your mouth. because they have destroyed many who are at peace.

13 A curse on slanderers and the deceitful,

14 Slander has shaken up many people, scattered them from nation to nation, demolished mighty cities, and overthrown the houses of dignitaries.
