Sirach 28:8 In-Context

6 Remember thy end, and let enmity cease; corruption and death, and abide in the commandments.
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.
