There were, too, other reasons for increasing the efficiency of the Levitical order by lengthening their term of service and adding to their numbers. The establishment of the Pentateuch as the sacred code of Judaism imposed new duties on priests and Levites alike. The people needed teachers and interpreters of the numerous minute and complicated rules by which they were to govern their daily life. Judges were needed to apply the laws in civil and criminal cases. The Temple ministers were the natural authorities on the Torah; they had a chief interest in expounding and enforcing it. But in these matters also the priests seem to have left the new duties to the Levites. Apparently the first “scribes,” or professional students of the Law, were mainly Levites. There were priests among them, notably the great father of the order, “Ezra the priest the scribe,” but the priestly families took little share in this new work. The origin of the educational and judicial functions of the Levites had also come to be ascribed to the great kings of Judah. A Levitical scribe is mentioned in the time of David.(110) In the account of Josiah’s reign we are expressly told that “of the Levites there were scribes, and officers, and porters”; and they are described as “the Levites that taught all Israel.”(111) In the same context we have the traditional authority and justification for this new departure. One of the chief duties imposed upon the Levites by the Law was the care and carriage of the Tabernacle and its furniture during the wanderings in the wilderness. Josiah, however, bids the Levites “put the holy ark in the house which Solomon the son of David, king of Israel, did build; there shall no more be a burden upon your shoulders; now serve the Lord your God and His people Israel.”(112) In other words, “You are relieved of a large part of your old duties, and therefore have time to undertake new ones.” The immediate application of this principle seems to be that a section of the Levites should do all the menial work of the sacrifices, and so leave the priests, and singers, and porters free for their own special service; but the same argument would be found convenient and conclusive whenever the priests desired to impose any new functions on the Levites.
