1 tn Heb “on the bone of this day.” The expression means “the substance of the day,” the day itself, the very day (S. R. Driver, Exodus, 95).
2 tn The word is “armies” or “divisions” (see Exod 6:26 and the note there; cf. also 7:4). The narrative will continue to portray Israel as a mighty army, marching forth in its divisions.
3 tn See Exod 12:14.
4 tn “month” has been supplied.
5 sn God chose to guide the people with a pillar of cloud in the day and one of fire at night, or, as a pillar of cloud and fire, since they represented his presence. God had already appeared to Moses in the fire of the bush, and so here again is revelation with fire. Whatever the exact nature of these things, they formed direct, visible revelations from God, who was guiding the people in a clear and unambiguous way. Both clouds and fire would again and again represent the presence of God in his power and majesty, guiding and protecting his people, by judging their enemies.
6 tn The infinitive construct here indicates the result of these manifestations – “so that they went” or “could go.”
7 tn These are adverbial accusatives of time.
8 tn This is an adverbial accusative of time, indicating that work may be done for six days out of the week.
9 tn The form is a Niphal imperfect; it has the nuance of permission in this sentence, for the sentence is simply saying that the six days are work days – that is when work may be done.
10 tn The expression is שַׁבַּת שַׁבָּתוֹן (shabbat shabbaton), “a Sabbath of entire rest,” or better, “a sabbath of complete desisting” (U. Cassuto, Exodus, 404). The second noun, the modifying genitive, is an abstract noun. The repetition provides the superlative idea that complete rest is the order of the day.
11 tn This is an adverbial accusative of time.
12 tn The word is קֹדֶשׁ (qodesh, “holiness”). S. R. Driver suggests that the word was transposed, and the line should read: “a sabbath of entire rest, holy to Jehovah” (Exodus, 379). But the word may simply be taken as a substitution for “holy day.”
