1 sn The firstborn were those that were essentially redeemed from death in Egypt when the blood was put on the doors. So in the very real sense they belonged to God (Exod 13:2,12). The firstborn was one who stood in special relationship to the father, being the successive offspring. Here, the Levites would stand in for the firstborn in that special role and special relationship. God also made it clear that the nation of Israel was his firstborn son (Exod 4:22-23), and so they stood in that relationship before all the nations. The tribe of Reuben was to have been the firstborn tribe, but in view of the presumptuous attempt to take over the leadership through pagan methods (Gen 35:22; 49:3-4), was passed over. The tribes of Levi and Simeon were also put down for their ancestors’ activities, but sanctuary service was still given to Levi.
2 tn The conjunction may be taken as explicative or epexegetical, and so rendered “namely; even; that is,” or it may be taken as emphatic conjunction, and translated “especially.”
3 tn The vav (ו) is taken here in its alternative use and translated “or.”
4 tn The form is the perfect tense with vav (ו) consecutive. After the instruction imperfects, this form could be given the same nuance, or more likely, subordinated as a purpose or result clause.
5 tn The verb “to be” (הָיָה, hayah) has the meaning “to become” when followed by the preposition lamed (ל).

Coats, “Moses in Midian,” JBL 92 (1973): 3-10; B. Mazar, “The Sanctuary of Arad and the Family of Hobab the Kenite,” JNES 24 (1965): 297-303; and T. C. Mitchell, “The Meaning of the Noun h£tn in the Old Testament,” VT 19 (1969): 93-112.
7 sn There is a problem with the identity of Hobab. The MT says that he is the son of Reuel, making him the brother-in-law of Moses. But Judg 4:11 says he is the father-in-law. In Judg 1:16; 4:11 Hobab is traced to the Kenites, but in Exod 3:1 and 18:1 Jethro (Reuel) is priest of Midian. Jethro is identified with Reuel on the basis of Exod 2:18 and 3:1, and so Hobab becomes Moses’ חֹתֵן (khoten), a relative by marriage and perhaps brother-in-law. There is not enough information to decide on the identity and relationships involved here. Some suggest that there is one person with the three names (G. B. Gray, Numbers [ICC], 93); others suggest Hobab is a family name (R. F. Johnson, IDB 2:615), and some suggest that the expression “the son of Reuel the Midianite” had dropped out of the genealogy of Judges, leading to the conflict (J. Crichton, ISBE 2:1055). If Hobab is the same as Jethro, then Exod 18:27 does not make much sense, for Jethro did go home. On this basis many conclude Hobab is a brother-in-law. This would mean that after Jethro returned home, Moses conversed with Hobab, his brother-in-law. For more discussion, see the articles and the commentaries.
8 tn The verb is the Hiphil of the root “to be good” (יָטַב, yatav); it may be translated “treat well, deal favorably, generously with.” Here it is a perfect tense with vav (ו) following the imperative, showing a sequence in the verbal ideas.
9 tn The Hebrew text simply has “has spoken good” for Israel.
10 sn Salt was used in all the offerings; its importance as a preservative made it a natural symbol for the covenant which was established by sacrifice. Even general agreements were attested by sacrifice, and the phrase “covenant of salt” speaks of such agreements as binding and irrevocable. Note the expression in Ezra 4:14, “we have been salted with the salt of the palace.” See further J. F. Ross, IDB 4:167.
11 tn The verb in this clause is the Hiphil perfect with a vav (ו) consecutive; it has the same force as an imperfect of instruction: “when…then you are to offer up.”
