Rashi on Genesis 43:14/רש"י על בראשית מ״ג:י״ד

1ואל שדי AND GOD ALMIGHTY — Now you lack nothing except prayer, and therefore I pray for you (Genesis Rabbah 91:11).

2אל שדי God שֶׁ-דַּי who gives plenteous mercy and in whose hand is sufficient power to give — may He give you mercy. This is the real meaning of the words. A Midrashic explanation is: He who said to the Universe, “Enough!”, may He say “Enough!” to my troubles. I have had no rest since my youth — trouble through Laban, trouble through Esau, the trouble of Rachel, the trouble of Dinah, the trouble of Joseph, the trouble of Simeon, the trouble of Benjamin (Genesis Rabbah 92:1).

3ושלח לכם means AND MAY HE RELEASE UNTO YOU, as the Targum renders it — may He release him from his bonds. It has the same meaning as (Exodus 21:26) “He shall let him go, יְשַׁלְּחֶנוּ (Piel) free”. It would not have been correct to translate it in the Targum by “and may he send to you your other brother”, because, as a matter of fact, they were going there where he was.

4את אחיכם YOUR BROTHER — This refers to Simeon.

5אחר THE OTHER ONE — The spirit of prophecy was diffused upon him so that he included Joseph also (Genesis Rabbah 92:3).

6ואני AND AS FOR ME — until you return I shall feel myself bereaved of my children being in constant suspense.

7כאשר שכלתי means EVEN AS I AM BEREAVED of Joseph and of Simeon

8שכלתי I SHALL BE BEREAVED of Benjamin.
