Sirach 28:9 In-Context

7 Remember the commandments, and bear no malice to thy neighbour: the covenant of the Highest, and wink at ignorance.

8 Abstain from strife, and thou shalt diminish thy sins: for a furious man will kindle strife,

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

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.
