There are many lessons here. One primary lesson is that we must love our fellow man, especially our family. We will elaborate on this later. Another lesson is how we must judge our fellow man favorably.
A little over a year ago, a menahel (principal) hired a magid shiur to teach in his yeshiva. It was a yeshiva for American bachurim who came to Eretz Yisrael to study Torah. The menahel said he would contact him when to begin giving shiurim.
The year began with yeshivos opening, but the menahel didn't contact this magid shiur. The magid shiur was quite insulted. He was hired for a position and never contacted, which means that the menahel probably found someone else to be the magid shiur. He also lost money. Other yeshivos wanted to hire him, but he turned them down because he thought he was secure with a job. But he controlled his anger and didn't rebuke the menahel for what he thought was a terrible deed.
At a later date, the menahel and the magid shiur met. The magid shiur asked the menahel what was happening with his position. The menahel replied, "When applicable, I will call you."
At this point, the magid shiur could not contain himself any longer. He said, "Didn't we make a contract that you would hire me at the beginning of the year? Why did you back down from the contract?"
The menahel replied, "Don't you know, due to the war (which began on Simchas Torah), the bachurim from America didn't yet return to Eretz Yisrael? The yeshiva didn't begin yet."
The magid shiur repeats this story and says that until that moment, he thought that the menahel mistreated him and that he caused him financial loss. He thought he was the tzaddik for controlling his anger and not rebuking the menahel. But as it turned out, he was the one who was wrong because he didn't judge his fellow man l'kaf zechus.
