Ulangan 2:14

2:14 Now the length of time it took for us to go from Kadesh Barnea to the crossing of Wadi Zered was thirty-eight years, time for all the military men of that generation to die, just as the Lord had vowed to them.

Ulangan 2:24

2:24 Get up, make your way across Wadi Arnon. Look! I have already delivered over to you Sihon the Amorite, king of Heshbon, ¹  and his land. Go ahead! Take it! Engage him in war!

Ulangan 2:36

2:36 From Aroer, ²  which is at the edge of Wadi Arnon (it is the city in the wadi), ³  all the way to Gilead there was not a town able to resist us – the Lord our God gave them all to us.

Ulangan 21:4

21:4 and bring the heifer down to a wadi with flowing water, ⁴  to a valley that is neither plowed nor sown. ⁵  There at the wadi they are to break the heifer’s neck.

[2:24]  ¹ sn Heshbon is the name of a prominent site (now Tell Hesba„n, about 7.5 mi [12 km] south southwest of Amman, Jordan). Sihon made it his capital after having driven Moab from the area and forced them south to the Arnon (Num 21:26-30). Heshbon is also mentioned in Deut 1:4.

[2:36]  ² sn Aroer. Now known as àAraáir on the northern edge of the Arnon river, Aroer marked the southern limit of Moab and, later, of the allotment of the tribe of Reuben (Josh 13:9, 16).

[2:36]  ³ tn Heb “the city in the wadi.” This enigmatic reference may refer to Ar or, more likely, to Aroer itself. Epexegetically the text might read, “From Aroer…, that is, the city in the wadi.” See D. L. Christensen, Deuteronomy 1–11 (WBC), 49.

[21:4]  ⁴ tn The combination “a wadi with flowing water” is necessary because a wadi (נַחַל, nakhal) was ordinarily a dry stream or riverbed. For this ritual, however, a perennial stream must be chosen so that there would be fresh, rushing water.

[21:4]  ⁵ sn The unworked heifer, fresh stream, and uncultivated valley speak of ritual purity – of freedom from human contamination.
