1 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 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.
3 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.
4 sn The unworked heifer, fresh stream, and uncultivated valley speak of ritual purity – of freedom from human contamination.
5 sn Mount Hermon. This is the famous peak at the southern end of the Anti-Lebanon mountain range known today as Jebel es-Sheik.
