1 tn Heb “And he said”; the word “replied” clarifies for English readers that speaker is God.
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.”
sn Here is the introduction of the main motif of the commission, which will be the explanation of the divine name. It will make little difference who the servant is or what that servant’s abilities might be, if God is present. The mention of God’s presence is not a simple catch-phrase; it represents abundant provisions to the believer (see below on v. 14).
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.
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.
sn This sign is also a promise from God – “you will serve God on this mountain.” It is given to Moses here as a goal, but a goal already achieved because it was a sign from God. Leading Israel out of Egypt would not be completed until they came to this mountain and served God. God does not give Moses details of what will take place on the road to Sinai, but he does give him the goal and glimpses of the defeat of Pharaoh. The rest will require Moses and the people to trust in this God who had a plan and who had the power to carry it out.
5 sn This passage has, of course, been taken literally by many devout Jews, and portions of the text have been encased in phylacteries and bound on the arm and forehead. B. Jacob (Exodus, 368), weighing the pros and cons of the literal or the figurative meaning, says that those who took it literally should not be looked down on for their symbolic work. In many cases, he continues, it is the spirit that kills and the letter makes alive – because people who argue against a literal usage do so to excuse lack of action. This is a rather interesting twist in the discussion. The point of the teaching was obviously meant to keep the Law of Yahweh in the minds of the people, to remind them of their duties.
6 tn That is, this ceremony.
7 tn Heb “for a sign.”
8 tn Heb “for a memorial.”
9 tn Heb “between your eyes” (KJV and ASV both similar); the same expression occurs in v. 16.
sn That these festivals and consecrations were to be signs and memorials is akin to the expressions used in the book of Proverbs (Prov 3:3, “bind them around your neck…write them on your heart”). The people were to use the festivals as outward and visible tokens to remind them to obey what the Law required.
10 tn The purpose of using this ceremony as a sign and a memorial is that the Law might be in their mouth. The imperfect tense, then, receives the classification of final imperfect in the purpose clause.
11 sn “Mouth” is a metonymy of cause; the point is that they should be ever talking about the Law as their guide as they go about their duties (see Deut 6:7; 11:19; Josh 1:8).
12 tn This causal clause gives the reason for what has just been instructed. Because Yahweh delivered them from bondage, he has the strongest claims on their life.
13 sn The instruction for the Sabbath at this point seems rather abrupt, but it follows logically the extended plans of building the sanctuary. B. Jacob, following some of the earlier treatments, suggests that these are specific rules given for the duration of the building of the sanctuary (Exodus, 844). The Sabbath day is a day of complete cessation; no labor or work could be done. The point here is that God’s covenant people must faithfully keep the sign of the covenant as a living commemoration of the finished work of Yahweh, and as an active part in their sanctification. See also H. Routtenberg, “The Laws of Sabbath: Biblical Sources,” Dor le Dor 6 (1977): 41-43, 99-101, 153-55, 204-6; G. Robinson, “The Idea of Rest in the OT and the Search for the Basic Character of Sabbath,” ZAW 92 (1980): 32-42; M. Tsevat, “The Basic Meaning of the Biblical Sabbath, ZAW 84 (1972): 447-59; M. T. Willshaw, “A Joyous Sign,” ExpTim 89 (1978): 179-80.
14 tn Or “your sanctifier.”
15 tn The expression again forms an adverbial accusative of time.
16 sn The word “rest” essentially means “to cease, stop.” So describing God as “resting” on the seventh day does not indicate that he was tired – he simply finished creation and then ceased or stopped. But in this verse is a very bold anthropomorphism in the form of the verb וַיִּנָּפַשׁ (vayyinnafash), a Niphal preterite from the root נָפַשׁ (nafash), the word that is related to “life, soul” or more specifically “breath, throat.” The verb is usually translated here as “he was refreshed,” offering a very human picture. It could also be rendered “he took breath” (S. R. Driver, Exodus, 345). Elsewhere the verb is used of people and animals. The anthropomorphism is clearly intended to teach people to stop and refresh themselves physically, spiritually, and emotionally on this day of rest.
