Numbers 3:7-8

3:7 They are responsible for his needs ¹  and the needs of the whole community before the tent of meeting, by attending ²  to the service of the tabernacle. 3:8 And they are responsible for all the furnishings of the tent of meeting, and for the needs of the Israelites, as they serve ³  in the tabernacle.

Numbers 3:10

3:10 So you are to appoint Aaron and his sons, and they will be responsible for their priesthood; ⁴  but the unauthorized person ⁵  who comes near must be put to death.”

[3:7]  ¹ tn The Hebrew text uses the perfect tense of שָׁמַר(shamar) with a vav (ו) consecutive to continue the instruction of the preceding verse. It may be translated “and they shall keep” or “they must/are to keep,” but in this context it refers to their appointed duties. The verb is followed by its cognate accusative – “they are to keep his keeping,” or as it is often translated, “his charge.” This would mean whatever Aaron needed them to do. But the noun is also used for the people in the next phrase, and so “charge” cannot be the meaning here. The verse is explaining that the Levites will have duties to perform to meet the needs of Aaron and the congregation.

[3:7]  ² tn The form is the Qal infinitive construct from עָבַד (’avad, “to serve, to work”); it is taken here as a verbal noun and means “by (or in) serving” (see R. J. Williams, Hebrew Syntax, 36, §195). This explains the verb “keep [his charge].” Here too the form is followed by a cognate accusative; they will be there to “serve the service” or “work the work.”

[3:8]  ³ tn The construction uses the infinitive construct (epexegetically) followed by its cognate accusative. It would convey “to serve the service of the tabernacle,” but more simply it may be rendered as “serving.” Their spiritual and practical service is to serve.

[3:10]  ⁴ tc The LXX includes the following words here: “and all things pertaining to the altar and within the veil.” Cf. Num 18:7.

[3:10]  ⁵ tn The word is זָר (zar), usually rendered “stranger, foreigner, pagan.” But in this context it simply refers to anyone who is not a Levite or a priest, an unauthorized person or intruder in the tabernacle. That person would be put to death.
