Midrash su Genesi 42:38

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).

Another interpretation (of Is. 65:25): THE WOLF AND THE LAMB SHALL FEED TOGETHER, < AND THE LION LIKE THE OX SHALL EAT STRAW >. (Ibid.:) THE WOLF: This is Benjamin, as stated (in Gen. 49:27): BENJAMIN IS A RAVENOUS WOLF. (Is. 65:25, cont.:) AND THE LAMB: This represents the tribes, as stated (in Jer. 50:17): ISRAEL IS A SCATTERED FLOCK…. (Is. 65:25, cont.:) SHALL FEED TOGETHER: When? When Benjamin went down with them, and Jacob said (in Gen. 42:38): LET NOT MY SON GO DOWN WITH YOU. When the hour arrived for him to go down with them, they placed him in their midst and watched over him. And so Joseph (in Gen. 43:29): LIFTED HIS EYES AND SAW HIS BROTHER BENJAMIN, THE SON OF HIS MOTHER…. (Is. 65:25, cont.:) THE LION: This is Judah, as stated (in Gen. 49:9): JUDAH IS A LION'S WHELP. (Is. 65:25, cont.:) LIKE THE OX: This is Joseph, since it is stated (in Deut. 33:17): LIKE A FIRSTLING BULL HE HAS MAJESTY. (Is. 65:25, cont.:) SHALL EAT STRAW, when they have been found eating together, as stated (in Gen. 43:33): AND THEY SAT DOWN BEFORE HIM FROM THE FIRST-BORN ACCORDING TO HIS BIRTHRIGHT. Therefore (in Gen. 46:28): NOW HE (Jacob) HAD SENT JUDAH AHEAD OF HIM.

(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."
