וַיֹּ֤אמֶר אֲלֵהֶם֙ יַעֲקֹ֣ב אֲבִיהֶ֔ם אֹתִ֖י שִׁכַּלְתֶּ֑ם יוֹסֵ֤ף אֵינֶ֙נּוּ֙ וְשִׁמְע֣וֹן אֵינֶ֔נּוּ וְאֶת־בִּנְיָמִ֣ן תִּקָּ֔חוּ עָלַ֖י הָי֥וּ כֻלָּֽנָה׃
און זײער פֿאָטער יעקב האָט צו זײ געזאָגט: איר האָט מיך באַרױבט פֿון מײַנע קינדער; יוֹסף איז מער ניטאָ, און שמעון איז ניטאָ, און בנימינען װילט איר אַװעקנעמען; דאָס אַלץ איז אױף מיר אױסגעגאַנגען.
Rashi
אתי שכלתם ME YE HAVE BEREAVED OF CHILDREN — The inference is that he suspected them of having slain or sold him (Simeon) as they had done to Joseph (Genesis Rabbah 91:9).
Radak
שכלתם, “you have bereaved;” a transitive mode, referring to a third person. The same construction appears when the prophet Samuel tells King Agag why he is about to kill him, saying שכלה נשים חרבך, “your sword has bereaved women” (Samuel I 15,33) Yaakov meant that “you my sons have caused me this problem with three of my sons.”
Sforno
עלי היו כלנה, none of these incidents has befallen you, whereas all of them have befallen me. It is therefore clear that the reason these tragedies have all befallen me must be your quarrels with one another. Therefore you are to blame for my being bereaved.
