Sirach 28:11

⁹A sinful man disquieteth friends, and maketh debate among them that be at peace.

¹⁰As 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.

— Sirach 28:11 —

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

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