Rashi on Numbers
ותהי מחצית העדה THE CONGREGATION’S HALF WAS so-and-so in number (as stated in the second half of this verse and in vv. 44—46).
Siftei Chakhamim
So much and so much. Not that it comes to teach us the total of this half, because this could be learned from the half-portion of those who partook in the war (v. 36). Rather this section continues until “Moshe took…” (v. 47) [teaching] that he took one fiftieth from this half and gave it to the Levites. Furthermore, if not so it should have said מחצית ["the half"], however ממחצית ["from the half"] indicates that what he took was from the half.
