Numbers 3:27-31

Context3:27 From Kohath came the family of the Amramites, the family of the Izharites, the family of the Hebronites, and the family of the Uzzielites; these were the families of the Kohathites. 1 3:28 Counting every male from a month old and upward, there were 8,600. They were responsible for the care 2 of the sanctuary. 3:29 The families of the Kohathites were to camp on the south side of the tabernacle. 3:30 Now the leader of the clan of the families of the Kohathites was Elizaphan son of Uzziel.
3:31 Their responsibilities included the ark, the table, the lampstand, the altars, and the utensils of the sanctuary with which they ministered, 3 the curtain, and all their service. 4
1 sn Both Moses and Aaron came from this line (6:16-20). During the Hebrew monarchy this branch of the line of Levi was exemplary in music (1 Chr 6:33-48). They were also helpful to Hezekiah in his reforms (1 Chr 29:12-14).
2 tn The construction here is a little different. The Hebrew text uses the participle in construct plural: שֹׁמְרֵי (shomÿrey, literally “keepers of”). The form specifies the duties of the 8,600 Kohathites. The genitive that follows this participle is the cognate מִשְׁמֶרֶת (mishmeret) that has been used before. So the expression indicates that they were responsible for the care of this part of the cult center. There is no reason to delete one of the forms (as does J. A. Paterson, Numbers, 42), for the repetition stresses the central importance of their work.
3 tn The verb is יְשָׁרְתוּ (yÿsharÿtu, “they will serve/minister”). The imperfect tense in this place, however, probably describes what the priests would do, what they used to do. The verb is in a relative clause: “which they would serve with them,” which should be changed to read “with which they would serve.”
4 tn The word is literally “its [their] service.” It describes all the implements that were there for the maintenance of these things.
