Numbers 18:1 assigns Aaron and his sons responsibility for the sanctuary — directly ties to Aaron's rod signifying his priestly authority.

Numbers 18:7 gives the priestly office to Aaron and his sons as a gift — strong thematic link to the rod that confirms Aaron's chosen priesthood.

Hebrews 5:4 cites the principle that Aaron's priesthood was divinely appointed, directly illustrated by the budding rod.
