Discovery BoxExodus 24:4 
Context24:4 and Moses wrote down all the words of the Lord. Early in the morning he built 1 an altar at the foot 2 of the mountain and arranged 3 twelve standing stones 4 – according to the twelve tribes of Israel.
Exodus 24:7
Context24:7 He took the Book of the Covenant 5 and read it aloud 6 to the people, and they said, “We are willing to do and obey 7 all that the Lord has spoken.”
1 tn The two preterites quite likely form a verbal hendiadys (the verb “to get up early” is frequently in such constructions). Literally it says, “and he got up early [in the morning] and he built”; this means “early [in the morning] he built.” The first verb becomes the adverb.
2 tn “under.”
3 tn The verb “arranged” is not in the Hebrew text but has been supplied to clarify exactly what Moses did with the twelve stones.
4 tn The thing numbered is found in the singular when the number is plural – “twelve standing-stone.” See GKC 433 §134.f. The “standing-stone” could be a small piece about a foot high, or a huge column higher than men. They served to commemorate treaties (Gen 32), or visions (Gen 28) or boundaries, or graves. Here it will function with the altar as a place of worship.
5 tn The noun “book” would be the scroll just written containing the laws of chaps. 20-23. On the basis of this scroll the covenant would be concluded here. The reading of this book would assure the people that it was the same that they had agreed to earlier. But now their statement of willingness to obey would be more binding, because their promise would be confirmed by a covenant of blood.
6 tn Heb “read it in the ears of.”
7 tn A second verb is now added to the people’s response, and it is clearly an imperfect and not a cohortative, lending support for the choice of desiderative imperfect in these commitments – “we want to obey.” This was their compliance with the covenant.
