Sirach 28:12

12 If thou blow the spark, it shall burn: if thou spit upon it, it shall be quenched: and both these come out of thy mouth.

Sirach 28:12 In-Context

10 As the matter of the fire is, so it burneth: and as a man's strength is, so is his wrath; and according to his riches his anger riseth; and the stronger they are which contend, the more they will be inflamed.

11 An hasty contention kindleth a fire: and an hasty fighting sheddeth blood.

12 If thou blow the spark, it shall burn: if thou spit upon it, it shall be quenched: and both these come out of thy mouth.

13 Curse the whisperer and doubletongued: for such have destroyed many that were at peace.

14 A backbiting tongue hath disquieted many, and driven them from nation to nation: strong cities hath it pulled down, and overthrown the houses of great men.
