Numbers 3

14-31. Number the children of Levi--They were numbered as well as the other tribes; but the enumeration was made on a different principle--for while in the other tribes the number of males was calculated from twenty years and upward [ Numbers 1:3 ], in that of Levi they were counted "from a month old and upward." The reason for the distinction is obvious. In the other tribes the survey was made for purposes of war [ Numbers 1:3 ], from which the Levites were totally exempt. But the Levites were appointed to a work on which they entered as soon as they were capable of instruction. They are mentioned under the names of Gershon, Kohath, and Merari, sons of Levi, and chiefs or ancestral heads of three subdivisions into which this tribe was distributed. Their duties were to assist in the conveyance of the tabernacle when the people were removing the various encampments, and to form its guard while stationary--the Gershonites being stationed on the west, the Kohathites on the south, and the families of Merari on the north. The Kohathites had the principal place about the tabernacle, and charge of the most precious and sacred things--a distinction with which they were honored, probably, because the Aaronic family belonged to this division of the Levitical tribe. The Gershonites, being the oldest, had the next honorable post assigned them, while the burden of the drudgery was thrown on the division of Merari.

32. chief--rather, "chiefs" of the Levites. Three persons are mentioned as chiefs of these respective divisions [ Numbers 3:24 Numbers 3:30 Numbers 3:35 ]. And Eleazar presided over them; whence he is called "the second priest" ( 2 Kings 25:18 ); and in the case of the high priest's absence from illness or other necessary occasions, he performed the duties ( 1 Kings 4:4 ).

38. those that encamp, &c.--That being the entrance side, it was the post of honor, and consequently reserved to Moses and the priestly family. But the sons of Moses had no station here.

39. twenty and two thousand--The result of this census, though made on conditions most advantageous to Levi, proved it to be by far the smallest in Israel. The separate numbers stated in Numbers 3:22 Numbers 3:28 Numbers 3:34 , when added together, amount to twenty-two thousand three hundred. The omission of the three hundred is variously accounted for--by some, because they might be first-born who were already devoted to God and could not be counted as substitutes; and by others, because in Scripture style, the sum is reckoned in round numbers. The most probable conjecture is, that as Hebrew letters are employed for figures, one letter was, in the course of transcription, taken for another of like form but smaller value.

40-51. Number all the first-born of the males of the children of Israel, &c.--The principle on which the enumeration of the Levites had been made was now to be applied to the other tribes. The number of their male children, from a month old and upward, was to be reckoned, in order that a comparison might be instituted with that of the Levites, for the formal adoption of the latter as substitutes for the first-born. The Levites, amounting to twenty-two thousand, were given in exchange for an equal number of the first-born from the other tribes, leaving an excess of two hundred seventy-three; and as there were no substitutes for these, they were redeemed at the rate of five shekels for each ( Numbers 18:15 Numbers 18:16 ). Every Israelite would naturally wish that his son might be redeemed by a Levite without the payment of this tax, and yet some would have to incur the expense, for there were not Levites enough to make an equal exchange. Jewish writers say the matter was determined by lot, in this manner: Moses put into an urn twenty-two thousand pieces of parchment, on each of which he wrote "a son of Levi," and two hundred seventy-three more, containing the words, "five shekels." These being shaken, he ordered each of the first-born to put in his hand and take out a slip. If it contained the first inscription, the boy was redeemed by a Levite; if the latter, the parent had to pay. The ransom money, which, reckoning the shekel at half a dollar, would amount to $2.50 each, was appropriated to the use of the sanctuary. The excess of the general over the Levitical first-born is so small, that the only way of accounting for it is, by supposing those first-born only were counted as were males remaining in their parents' household, or that those first-born only were numbered which had been born since the departure from Egypt, when God claimed all the first-born as his special property.

41. the cattle of the Levites--These, which they kept to graze on the glebes and meadows in the suburbs of their cities, to supply their families with dairy produce and animal food, were also taken as an equivalent for all the firstlings of the cattle which the Israelites at that time possessed. In consequence of this exchange the firstlings were not brought then, as afterwards, to the altar and the priests.
