[3:12] 1 tn Heb “And he said”; the word “replied” clarifies for English readers that speaker is God.
[3:12] 2 tn The particle כִּי (ki) has the asseverative use here, “surely, indeed,” which is frequently found with oaths (R. J. Williams, Hebrew Syntax, 73, §449). The imperfect tense אֶהְיֶה (’ehyeh) could be rendered as the future tense, “I will be” or the present tense “I am” with you. The future makes the better sense in this case, since the subject matter is the future mission. But since it is a stative verb, the form will also lend itself nicely to explaining the divine name – he is the One who is eternally present – “I am with you always.”
[3:12] 3 sn In view of Moses’ hesitancy, a sign is necessary to support the promise. A sign is often an unusual or miraculous event that introduces, authenticates, or illustrates the message. One expects a direct connection between the sign and the message (for a helpful discussion, see S. Porúbcan, “The Word ’OT in Isaia 7,14,” CBQ 22 [1960]: 144-49). In this passage the sign is a confirming one, i.e., when Israel worships at the mountain that will be the proof that God delivered them from Egypt. Thus, the purpose of the exodus that makes possible the worship will be to prove that it was God who brought it about. In the meantime, Moses will have to trust in Yahweh.
[3:12] 4 tn The verb תַּעַבְדוּן (ta’avdun, “you will serve”) is one of the foremost words for worship in the Torah. Keeping the commandments and serving Yahweh usually sum up the life of faith; the true worshiper seeks to obey him. The highest title anyone can have in the OT is “the servant of Yahweh.” The verb here could be rendered interpretively as “worship,” but it is better to keep it to the basic idea of serving because that emphasizes an important aspect of worship, and it highlights the change from Israel’s serving Egypt, which has been prominent in the earlier chapters. The words “and they” are supplied to clarify for English readers that the subject of the verb is plural (Moses and the people), unlike the other second person forms in vv. 10 and 12, which are singular.
