Exodus 18:12

1 tn The preterite with vav consecutive is here subordinated to the next verb as a temporal clause. The main point of the verse is what they said.
2 tn Heb “a man to his brother.”
3 tn The text has: מָן הוּא כִּי לאֹ יָדְעוּ מַה־הוּא (man hu’ ki lo’ yadÿ’u mah hu’). From this statement the name “manna” was given to the substance. מָן for “what” is not found in Hebrew, but appears in Syriac as a contraction of ma den, “what then?” In Aramaic and Arabic man is “what?” The word is used here apparently for the sake of etymology. B. S. Childs (Exodus [OTL], 274) follows the approach that any connections to words that actually meant “what?” are unnecessary, for it is a play on the name (whatever it may have been) and therefore related only by sound to the term being explained. This, however, presumes that a substance was known prior to this account – a point that Deuteronomy does not seem to allow. S. R. Driver says that it is not known how early the contraction came into use, but that this verse seems to reflect it (Exodus, 149). Probably one must simply accept that in the early Israelite period man meant “what?” There seems to be sufficient evidence to support this. See EA 286,5; UT 435; DNWSI 1:157.
4 sn B. Jacob (Exodus, 454-55) suggests that Moses was saying to them, “It is not manna. It is the food Yahweh has given you.” He comes to this conclusion based on the strange popular etymology from the interrogative word, noting that people do not call things “what?”
5 sn For other views see G. Vermès, “‘He Is the Bread’ Targum Neofiti Ex. 16:15,” SJLA 8 (1975): 139-46; and G. J. Cowling, “Targum Neofiti Ex. 16:15,” AJBA (1974-75): 93-105.
6 tn The verb is “and he took” (cf. KJV, ASV, NASB). It must have the sense of getting the animals for the sacrifice. The Syriac, Targum, and Vulgate have “offered.” But Cody argues because of the precise wording in the text Jethro did not offer the sacrifices but received them (A. Cody, “Exodus 18,12: Jethro Accepts a Covenant with the Israelites,” Bib 49 [1968]: 159-61).
7 sn Jethro brought offerings as if he were the one who had been delivered. The “burnt offering” is singular, to honor God first. The other sacrifices were intended for the invited guests to eat (a forerunner of the peace offering). See B. Jacob, Exodus, 498.
8 tn The word לֶחֶם (lekhem) here means the sacrifice and all the foods that were offered with it. The eating before God was part of covenantal ritual, for it signified that they were in communion with the Deity, and with one another.
