Musar su Genesi 37:26

And see another extremely awesome thing which unraveled itself in the course of time, measure for measure. For Joseph stumbled in the sin of lashon hara [against his brothers] as related in the Torah. And his brothers did not want, by any means, to forgive him, relating to him in the extreme of din, saying (Bereshith 37:20): "Let us go and kill him (that is: "Let us sic the dogs on him" and the like,) and they wished to sell him as a slave because of this, though Judah defended him and did not allow them to kill him, as it is written (Bereshith 37:26): "What profit if we kill our brother, etc." Still, he by no means wanted to forgive him, saying (Ibid. 27): "Let us go and sell him." And because of this, in the succeeding generations, when one of the seed of Judah stumbled in the issur of accepting lashon hara, the distinctive one of the seed of Joseph would by no means forgive him. And who is it that stumbled in this way? No less than our lord, King David, may peace be upon him, who believed the evil that Tziva spoke of Mefibosheth, and said (II Samuel 19:30): "You [Mefibosheth] and Tziva shall divide the field" — at which a Heavenly voice came forth and said: "Rechavam [of the seed of Judah] and Yaravam [of the seed of Joseph] shall divide the kingdom." And, as it is written in Scripture, that after the death of Solomon, Yaravam and all of Israel came to Rechavam and besought him to ease somewhat his yoke upon them and they would serve him, and he answered them (I Kings 12:14): "My father [Solomon] chastised you with whips, but I will chastise you with scorpion-thorns" — whereupon all of them answered (II Chronicles 10:16): "Each to your tents, O Israel," and they crowned Yaravam. And the underlying cause was David's acceptance of lashon hara. As our sages of blessed memory said: "If David had not accepted lashon hara, the kingdom of the house of David would not have been divided and Israel would not have served idolatry, and we would not have been exiled from our land." And all of this is "measure for measure," as we have written.

Some commentators even claim that the tribe of Yehudah had already begun its journey, but was forced to return in her honour. The author of צרור המור writes at the end of Parshat Beha-alotcha, that there was an element of מדה כנגד מדה in this, since it was Yehudah who had exclaimed at the time the brothers wanted to kill Joseph "מה בצע כי נהרוג את אחינו … לכו ונמכרנו" "what profit is there in killing our brother, let us rather sell him!" This comment was held against him (Genesis 37,26). Miriam, by her very nature ignored material gains, as is evident from the danger she put herself in when defying Pharaoh's instructions to kill all male Jewish babies. On the contrary, she actively helped them survive. The repetition of the statement ותחיינה את הילדים in Exodus 1,18, suggests that she provided victuals for them out of her personal funds. This is why she experienced the honour of the tribe of Yehudah returning to wait for her until she had been healed of her צרעת.
