A man who fights his brother will not have anyone to watch his back.
When you fight your brethren, you will fight alone on the day of your battle with the enemies.
A man who kills his brother will die of loneliness.
When two brothers fight, a stranger reaps the harvest.

Don’t fight your brother.
Don’t fight your brethren in Church.
Don’t fight your colleagues.
Don’t fight your spouse.

Lest the enemy moves in and sacks you from your house.
Lest Satan move in and destroy you.
Lest you create a crack from where your house is destroyed.
Lest you make room for the destruction of your union.
