John Gill Commentary Numbers 17:9

"And Moses brought out all the rods from before Jehovah unto all the children of Israel: and they looked, and took every man his rod." — Numbers 17:9 (ASV)

And Moses brought out all the rods from before the Lord, unto
all the children of Israel
He brought them out of the holy place, and showed them to the princes of the several tribes:

and they looked, and took every man his rod ;
which they knew by their names upon them; by their own handwriting, as Aben Ezra; for though Moses is bid to write their names on them, (Numbers 17:2Numbers 17:3) ; yet no more may be meant by that than that he should order them to be written, and take care that they were.
