Musar su Genesi 44:9

And Judah said (Ibid. 43:9): "If I do not bring him [Benjamin] to you and present him to you [alive], I shall have sinned against you all the days," Judah going surety both in this world and the next, and through this, experiencing great suffering, more than all of the other brothers, as written in Parshath Vayigash. The reason for this is that he caused Joseph's being sold as a slave. In truth, Judah was the most eminent of the brothers, and he should have strengthened himself to return Joseph to his father, wherefore he was punished by Heaven by having to go surety for a different brother [Benjamin], to bring him to his father. And in this, he strengthened himself with all his power, and he also acquiesced in prostrating himself before the lord of the land to be taken as a slave, so that his brother could return home to his father. And all the other brothers who acquiesced in the sale were made to undergo great sorrow by acquiescing in becoming slaves themselves, as it is written (Ibid. 44:9): "And we, too, shall be slaves to my lord." And also (Ibid. 50:18): "And his brothers also went, and they fell before him [Joseph] and they said: 'Behold, we are your slaves.'"
