Numbers 4:28

4:28 This is the service of the families of the Gershonites concerning the tent of meeting. Their responsibilities will be under the authority ¹  of Ithamar son of Aaron the priest. ² 

Numbers 4:3

4:3 from thirty years old and upward to fifty years old, all who enter the company ³  to do the work in the tent of meeting.

¹ tn Or “the direction” (NASB, TEV); Heb “under/by the hand of.” The word “hand” is often used idiomatically for “power” or “authority.” So also in vv. 33, 37, 45, 48.

² sn The material here suggests that Eleazar had heavier responsibilities than Ithamar, Aaron’s fourth and youngest son. It is the first indication that the Zadokite Levites would take precedence over the Ithamar Levites (see 1 Chr 24:3-6).

³ tn The word “company” is literally “host, army” (צָבָא, tsava’). The repetition of similar expressions makes the translation difficult: Heb “all [who] come to the host to do work in the tent.”
