Keluaran 19:2

19:2 After they journeyed ¹  from Rephidim, they came to the Desert of Sinai, and they camped in the desert; Israel camped there in front of the mountain. ² 

Keluaran 8:27

8:27 We must go ³  on a three-day journey ⁴  into the desert and sacrifice ⁵  to the Lord our God, just as he is telling us.” ⁶ 

[19:2]  ¹ tn The form is a preterite with vav (ו) consecutive, “and they journeyed.” It is here subordinated to the next clause as a temporal clause. But since the action of this temporal clause preceded the actions recorded in v. 1, a translation of “after” will keep the sequence in order. Verse 2 adds details to the summary in v. 1.

[19:2]  ² sn The mountain is Mount Sinai, the mountain of God, the place where God had met and called Moses and had promised that they would be here to worship him. If this mountain is Jebel Musa, the traditional site of Sinai, then the plain in front of it would be Er-Rahah, about a mile and a half long by half a mile wide, fronting the mountain on the NW side (S. R. Driver, Exodus, 169). The plain itself is about 5000 feet above sea level. A mountain on the west side of the Arabian Peninsula has also been suggested as a possible site.

[8:27]  ³ tn The verb נֵלֵךְ (nelekh) is a Qal imperfect of the verb הָלַךְ (halakh). Here it should be given the modal nuance of obligation: “we must go.”

[8:27]  ⁴ tn This clause is placed first in the sentence to stress the distance required. דֶּרֶךְ (derekh) is an adverbial accusative specifying how far they must go. It is in construct, so “three days” modifies it. It is a “journey of three days,” or, “a three day journey.”

[8:27]  ⁵ tn The form is the perfect tense with a vav (ו) consecutive; it follows in the sequence: we must go…and then [must] sacrifice.”

[8:27]  ⁶ tn The form is the imperfect tense. It could be future: “as he will tell us,” but it also could be the progressive imperfect if this is now what God is telling them to do: “as he is telling us.”
