Bilangan 18:2

18:2 “Bring with you your brothers, the tribe of Levi, the tribe of your father, so that they may join ¹  with you and minister to you while ²  you and your sons with you are before the tent of the testimony.

Bilangan 18:4

18:4 They must join ³  with you, and they will be responsible for the care of the tent of meeting, for all the service of the tent, but no unauthorized person ⁴  may approach you.

[18:2]  ¹ sn The verb forms a wordplay on the name Levi, and makes an allusion to the naming of the tribe Levi by Leah in the book of Genesis. There Leah hoped that with the birth of Levi her husband would be attached to her. Here, with the selection of the tribe to serve in the sanctuary, there is the wordplay again showing that the Levites will be attached to Aaron and the priests. The verb is יִלָּווּ (yillavu), which forms a nice wordplay with Levi (לֵוִי). The tribe will now be attached to the sanctuary. The verb is the imperfect with a vav (ו) that shows volitive sequence after the imperative, here indicating a purpose clause.

[18:2]  ² tn The clause is a circumstantial clause because the disjunctive vav (ו) is on a nonverb to start the clause.

[18:4]  ³ tn Now the sentence uses the Niphal perfect with a vav (ו) consecutive from the same root לָוָה (lavah).

[18:4]  ⁴ tn The word is “stranger, alien,” but it can also mean Israelites here.
