Numbers 3:48
And thou shalt give the money, wherewith the odd number of them is to be redeemed, unto Aaron and to his sons.
And thou shalt give the money, wherewith the odd number of them is to be redeemed,.... Or the superfluous number, the number of them that exceeded the Levites, namely, two hundred seventy three; the price of their redemption is ordered to be given
unto Aaron, and to his sons; since the Levites were taken in lieu of the firstborn, whose redemption money belonged to the priests; and seeing the Levites were given to Aaron and his sons on that consideration, and there being a deficiency of them to answer to the firstborn, it was but right and just that the redemption price of the superfluous number should be paid to them.
