Why does the Torah here write "Aharon u'Vanav" (in the plural) and in the following Pasuk, "b'Yad Isamar"?
1.
Rashi: Pasuk 28 explains Pasuk 27, as if to say 'which of the sons? Isamar'. 1
2.
Ramban, Moshav Zekeinim: The current Pasuk refers to Aharon and his sons, who appointed every ben Gershon 2 to his specific task, 3 including whether he would sing or whether he would stand guard. Also when they traveled, they did not dismantle or load on to the wagons, until they received the go-ahead from Aharon and his sons. 4
