Numbers 20:26

את בגדיו [AND STRIP AARON OF] HIS GARMENTS — i.e., the garments of the high priesthood. — He clothed him in these and stripped them off him to place them on his son in his presence. He (Moses) said to him (Aaron), “Enter the cave”, and he entered. — He saw a bed already made (more lit., outspread, i.e., with its sheets, etc.) and a light burning. He said to him, “Ascend the bed”, and he ascended. — “Stretch out your hands”, and he stretched them out. — “Close your mouth”, and he closed it. — “Close your eyes”, and he closed them. At that moment Moses longed for that self-same death, and this is what was said to him (Deuteronomy 32:50), “[And die] … as Aaron thy brother died” — the death, for which you longed (Siphre on that verse).

וְהַפְשֵׁ֤ט אֶֽת־אַהֲרֹן֙ אֶת־בְּגָדָ֔יו וְהִלְבַּשְׁתָּ֖ם אֶת־אֶלְעָזָ֣ר בְּנ֑וֹ וְאַהֲרֹ֥ן יֵאָסֵ֖ף וּמֵ֥ת שָֽׁם׃

and strip Aharon of his garments, and put them upon El῾azar his son: and Aharon shall be gathered to his people, and shall die there.
