출애굽기 6:26 해설: Tze'enah Ure'enah, Rashi, Chizkuni & Rashbam

“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.

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).

הוא אהרן ומשה, whenever Moses and Aaron are mentioned in context of their respective ages, Aaron is mentioned first as he was the senior of the two. When these two brothers are mentioned in context of their respective status amongst the people, Moses is mentioned first, as in verse 27. After all, Moses took out the Israelites from slavery in Egypt.
