Midrash Tanchuma
Who was one such guarantor? Judah, for he said: Send the lad with me … I will be surety for him (Gen. 43:8–9). And he (Jacob) said: “My son shall not go down with you … if harm befall him by the way in which ye go (ibid. 42:38). From this verse, you may conclude that Satan brings charges against one who embarks on a journey.
Midrash Tanchuma
Shall feed together. When did that occur? When Benjamin descended with his brothers. Though Jacob had said: My son shall not go down with you (Gen. 42:38), yet when the time for departure came, he did descend with them. They placed him between themselves and guarded him. And thus it says: Joseph lifted up his eyes, and saw Benjamin his brother, his mother’s son (Gen. 43:29).
Mekhilta DeRabbi Yishmael
(Exodus 21:23) "And if there be ason": "Ason" is death. And though there is no proof for this, it is intimated in (Genesis 42:38) "and he will be met with ason."
