Comentario sobre Números 17:17

TWELVE RODS. Aaron’s rod was one of the twelve, since it does not say: “and you shall take a rod for the house of Levi and write Aaron’s name upon it” [but instead it says in the following verse, And thou shalt write Aaron’s name upon the rod of Levi]; for he was included in the number mentioned. Thus Joseph was counted as only one tribe [and not as two separate tribes — Ephraim and Menasheh], the reason being that the tribes of Israel are always counted as twelve, and because He counted Levi [here as one tribe], He counted Joseph as only one. I will explain this further in Seder V’zoth Habrachah,¹⁹¹Deuteronomy 33:6. if G-d will bless me to reach it [in my commentary].

דבר אל בני ישראל וקח מאתם, "speak to the children of Israel and take from them, etc." The expressions דבר plus קח suggest that we are speaking about two separate subjects. G'd said דבר, referring to the fact that 1) the Israelites were to bring one rod representing their respective tribes; 2) Moses was to accept these rods from them. Although the Torah did not spell out who was to bring these rods to Moses, the letter ו at the beginning of the words וקח alludes to this. [The problem is that the Torah did not spell out exactly what it was that Moses was to take from the children of Israel. Ed.] An additional reason for the Torah to write וקח with the extra letter ו may be that this demonstration was additional to the conversion of the 250 censers into covers for the altar which had also been described as being a memorial to what happened to Korach and associates. The people had to be given visual evidence that G'd had chosen Aaron.

שנים עשר מטות, “twelve staffs.” Aaron’s staff was included in the twelve, seeing that it does not say that Moses should take the staff of Levi and inscribe Aaron’s name on it, but it does say: “inscribe Aaron’s name on the staff representing the tribe of Levi.” In other words, there already was a staff representing the tribe of Levi. The tribe of Joseph was represented here by only one staff as it is axiomatic that the total number of tribes in the Jewish people would be 12 at all times.
