The first-born are found to exceed the number of the Levites by two hundred and seventy-three; and for their redemption Moses takes "five shekels apiece by the poll; after the shekel of the sanctuary." The money thus collected is given unto Aaron and his sons. The method of redemption here presented, purely arbitrary in respect of the sum appointed for the ransom of each life, is fitly contrasted by the Apostle Peter with that of the Christian dispensation. He adopts the word _redeem_, taking it over from the old economy, but says, "Ye were redeemed not with corruptible things, with silver or gold, from your vain manner of life handed down from your fathers." And the difference is not only that the Christian is redeemed with the precious blood of Christ, but this also, that, while the first-born Israelite was relieved of certain parts of the holy service which might have been claimed of him by Jehovah, it is for sacred service, "to be a holy priesthood to offer up spiritual sacrifices," Christians are redeemed. In the one case exemption, in the other case consecration is the end. The difference is indeed great, and shows how much the two covenants are in contrast with each other. It is not to enable us to escape any of the duties or obligations of life Christ has given Himself for us. It is to make us fit for those duties, to bring us fully under those obligations, to purify us that we may serve God with our bodies and spirits which are His. A passage in Exodus (xiii. 11 f.) must not be overlooked in connection with that presently under consideration. The enactment there is to the effect that when Israel is brought into the land of the Canaanites every first-born of beasts shall be set apart unto the Lord, the firstling of an ass shall be redeemed with a lamb or killed, and all first-born children shall be redeemed. Here the singular point is that the law is deferred, and does not come into operation till the settlement in Canaan. Either this was set aside for the provisions made in Numbers, or these are to be interpreted by it. The difficulties of the former view are greatly increased by the mention of the "shekel of the sanctuary," which seems to imply a settled medium of exchange, hardly possible in the wilderness.
