the sinful man was protected from the punishment of the judge in consequence of this covering. In this way כּפר has acquired the meaning λύτρον, a payment by which the guilty are redeemed (Exo 21:30; Num 35:31); and this is the meaning which it has in the passage before us, where the soul is said to be protected by the copher, so as to be able to come without danger into the presence of the holy God (Num 8:19. See Oehler in Herzog's Cycl.). Such an approach to God took place at the numbering of the people for the purpose of enrolling them in the army of Jehovah (Num 1:3, cf. Exo 7:4; Exo 12:41). Hence “every one who passed over to those that were numbered,” who was enrolled among them, i.e., in the army of Jehovah, - that is to say, every male Israelite of 20 years old and upwards (Exo 30:14), - was to pay half a shekel of the sanctuary as atonement-money; the rich no more, the poor no less (Exo 30:15), because all were equal in the sight of Jehovah; and this payment was to be a “heave” (terumah, see Exo 25:2) for Jehovah for the expiation of the souls. The shekel of the sanctuary, which contained 20 gerahs, was no doubt the original shekel of full weight, as distinguished from the lighter shekel which was current in ordinary use. In Exo 38:26 the half shekel is called בּקע, lit., the split, i.e., half, from בּקע to split; and we find it mentioned as early as the time of the patriarchs as a weight in common use for valuing gold (Gen 24:22), so that, no doubt, even at that time there were distinct silver pieces of this weight, which were probably called shekels when employed for purposes of trade, since the word shekel itself does not denote any particular weight, as we may perceive at once form a comparison of 1Ki 10:17 and 2Ch 9:16, at least so far as later times are concerned. The sacred shekel, to judge from the weight of Maccabean shekels, which are in existence still, and vary from 256 to 272 Parisian grains, weighed 274 grains, and therefore, according to present valuation, would be worth 26 groschen (about 2s. 7d.), so that the half-shekel of bekah would be 13 groschen (1s. 3 1/2d.).
Verse 16
This atonement-money Moses was to appropriate to the work of the sanctuary (cf. Exo 38:25-28, where the amount and appropriation are reported). Through this appropriation it became “a memorial to the children of Israel before the Lord to expiate their souls,” i.e., a permanent reminder of their expiation before the Lord, who would henceforth treat
