All in this together... loving your neighbour as civic responsibility

(17) Thou shalt not hate thy brother in thy heart; thou shalt surely rebuke thy neighbour, and not bear sin because of him. (18) Thou shalt not take vengeance, nor bear any grudge against the children of thy people, but thou shalt love thy neighbour as thyself: I am the LORD.

“When one man sins will you be angry with the whole community?” (Numbers 16:22) Rabbi Shimon bar Yochai taught: This may be compared to the case of men on a ship, one of whom took a borer and began boring beneath his own place. His fellow travellers said to him: “What are you doing?” Said he to them: “What does that matter to you? Am I not boring under my own seat? Said they: “But the water will come up and flood the ship for all of us!”

(8) When thou buildest a new house, then thou shalt make a parapet for thy roof, that thou bring not blood upon thy house, if any man fall from thence.

It says “you shall not take vengeance, nor bear a grudge”. (Leviticus 19:18)

Revenge is illustrated by the following example.

One said to his fellow “Lend me your sickle.” And he said “No”. The next day, he [the one who had refused to lend the sickle] said to the other person “Lend me your axe.” If he said to him “I will not lend to you just as you did not lend to me.” That is revenge.

What is bearing a grudge?

If one said to his fellow: “Lend me your axe” and he said “No”. And the next day, he [the one who had refused to lend his axe] said to the other man “Lend me your robe.” If the first one said to him “Here it is. I am not like you who would not lend to me.” That is bearing a grudge.
