Sila ang Aaron at Moises na sinabihan ng Walang-Hanggan: “Ilabas ninyo ang mga anak ni Israel mula sa lupain ng Egipto ayon sa kanilang mga hukbo.”
Tze'enah Ure'enah
“It is the same Aaron and Moses” [6:26]. The verse sometimes mentions Aaron first. It wants to teach us that Aaron was also important, just like Moses, since he was older than Moses. Moses was much more important than Aaron with regard to prophecy.7Bahya, Exodus, 6:26.
Rashi
הוא אהרן ומשה THESE ARE THAT AARON AND MOSES who are mentioned above where it states (v. 20) that Jochebed bore them to Amram. הוא אהרן ומשה There are some passages where Scripture mentions Aaron before Moses (as here) and other passages where it mentions Moses before Aaron; this is done in order to indicate that they were equal in all respects (more lit., that they weighed alike) (Mekhilta).
Rashbam
הוא אהרן ומשה, Aaron, the one born prior to Moses is described as הוא, i.e. a distinction, whereas the same distinction expressed by the same word הוא is also applied to Moses . Both were singled out as G’d’s messengers.
