3:14-39 The Levites were in three classes, according to the sons of Levi; Gershon, Kohath, and Merari; and these were subdivided into families. The posterity of Moses were not at all honoured or privileged, but stood upon the level with other Levites; thus it was plain, that Moses did not seek the advancement of his own family, or to secure any honours to it. The tribe of Levi was by much the least of all the tribes. God's chosen are but a little flock in comparison with the world.Of the Levites, the Kohathites, the kinsmen of Moses and Aaron, and the most numerous, have the most important charge confided to them, namely, that of the ark, the altars, and the more especially sacred furniture generally. 32. chief—rather, "chiefs" of the Levites. Three persons are mentioned as chiefs of these respective divisions [Nu 3:24, 30, 35]. And Eleazar presided over them; whence he is called "the second priest" (2Ki 25:18); and in the case of the high priest's absence from illness or other necessary occasions, he performed the duties (1Ki 4:4).

shall be Zuriel the son of Abihail; of whom we read nowhere else, nor is it certain of which family he was, whether of the Mahlites or Mushites:

these shall pitch on the side of the tabernacle northward; to the left of it, between that and the camp of Dan.

And the chief of the house of the father of the families of Merari was Zuriel the son of Abihail: these shall pitch on the side of the tabernacle northward.
