This redemption money (see the marginal references) would perhaps be exacted from the parents of the "youngest" children of the 22,273 Numbers 3:43. The cattle of the Levites was doubtless taken in the gross as an equivalent for the first-born cattle of the other tribes, which of course, no less than the first-born of men, belonged to the Lord; and in future would have to be redeemed Numbers 18:15; Deuteronomy 15:19.

And the Lord spake unto Moses,.... After the number was taken, and gave him directions what to do upon it:

saying; as follows.

And the LORD spake unto Moses, saying,

3:40-51 The number of the first-born, and that of the Levites, came near to each other. Known unto God are all his works beforehand; there is an exact proportion between them, and so it will appear, when they are compared together. The small number of first-born, over and above the number of the Levites, were to be redeemed, and the redemption-money given to Aaron. The church is called the church of the first-born, which is redeemed, not as they were, with silver and gold; but, being devoted by sin to the justice of God, is ransomed with the precious blood of the Son of God. All men are the Lord's by creation, and all true christians are his by redemption. Each should know his own post and duty; nor can any service required by such a Master be rightly accounted mean or hard.
