האָט משה אַרױסגעטראָגן אַלע שטעקנס פֿון פֿאַר גאָט צו אַלע קינדער פֿון ישׂראל, און זײ האָבן איבערגעקוקט, און גענומען איטלעכער זײַן שטעקן.
Sforno
ויראו ויקחו איש מטהו. So there will be an indication for their tribe.
Rabbeinu Bahya
ויראו ויקח איש מטהו, “when they saw, each (tribal representative) took his own staff.” Each one knew which was his staff as they had inscribed their names on it.
Tze'enah Ure'enah
“Each identified and recovered his staff” [17:24]. Each one identified his staff, because each one had written his name on his staff. The Holy One commanded that Aaron’s staff should be placed in the Tent of Meeting, as a sign against the people who wanted to argue against the priesthood.39Rashi, Numbers, 17:25.
