Numbers 3:51

And Moses gave the money of them that were redeemed ,.... That were redeemed this way, and not by Levites, as in Numbers 3:49 , but by money, paying five shekels a head:

unto Aaron and his sons ; to whom the Levites were given; and this money, as a recompence for the deficiency of the number of them, to answer to the firstborn exchanged for them:

according to the word of the Lord ; Numbers 3:48 ,

as the Lord commanded Moses ; so did he, being a faithful servant in all things in the house of God; he did not convert it to his own use, or to any other use than to what God had appointed it.
