It is doubtful, whether the families of the priests and sacrificial servants who traced back their lineage to Levi, the son of Jacob (p. 197), and were now united by David and Solomon for service at the sacred tabernacle, for sacrifice and attendance at the temple, had of antiquity formed a separate tribe, which afterwards became dispersed (I. 488),--or if this tribe first was united under the impression made by the idea of true priesthood, which those writings denoted as an example and pattern, and under the influence of the change introduced by the foundation of a central-point for the worship of Israel in the tabernacle of David, and then in the temple of Solomon, for the priestly families scattered through the land, by means of a gradual union of the priestly families; at all events, a position at least equal in dignity to the rest of the tribes ought to be found for the tribe of Levi, which knew the will and law of Jehovah, and the correct mode of sacrifice. It was not indeed possible in Israel to give the first and most ancient place to the tribe of the priests, as has been done in other nations where a division of orders has crystallised into hereditary tribes. In the memory of the nation Reuben was the first-born tribe, _i.e._ the complex of the oldest families, the oldest element of the nation, and the importance of the tribes derived from Joseph and the tribe of Judah in and after the conquest of Canaan was so firmly fixed that the tribe of Levi could not hope to contend with them successfully in the question of antiquity. But what was wanting in rank of derivation could be made up by special blessings given by Jehovah, and by peculiar sanctity. According to an old conception the first-born male belonged to Jehovah. In the sketch of the fortunes of Israel and of the law, Jehovah says to Moses, he will accept the tribe of Levi in place of the first-born males of the people. The number of the first-born males of one month old of all the other tribes was taken--they reached 22,373; the number of all the men and boys down to the age of one month in the tribe of Levi was 22,000. These 22,000 Levites Jehovah took in the place of the first-born of the people, and the remaining 373 were ransomed from Jehovah at the price of five shekels of silver for each person.[368] Thus the Levites were raised by Jehovah to be the first-born tribe of Israel. Levi was the tribe which Jehovah had selected for his service, the chosen tribe of a chosen nation. Moses and Aaron were of this tribe, and if, instead of a few families who stood beside Moses when he led Israel out of Egypt, and restored the worship of the tribal deity, the whole tribe of Levi was represented as active in his behalf, and as a supporter of Moses, the consecration of age was not wanting to this tribe, and reverence was naturally paid to it in return for such ancient services.
