Ben Sira 28:12

12 If you blow on a spark, it will glow; if you spit on it, it will be put out; and both come out of your mouth.

Ben Sira 28:12 In-Context

10 In proportion to the fuel for the fire, so will be the burning, and in proportion to the obstinacy of strife will be the burning; in proportion to the strength of the man will be his anger, and in proportion to his wealth he will heighten his wrath.
11 A hasty quarrel kindles fire, and urgent strife sheds blood.
12 If you blow on a spark, it will glow; if you spit on it, it will be put out; and both come out of your mouth.
13 Curse the whisperer and deceiver, for he has destroyed many who were at peace.
14 Slander has shaken many, and scattered them from nation to nation, and destroyed strong cities, and overturned the houses of great men.
