Deuteronomy 21:4

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

Deuteronomy 21:6

21:6 and all the elders of that city nearest the corpse must wash their hands over the heifer whose neck was broken in the valley.

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.

sn The unworked heifer, fresh stream, and uncultivated valley speak of ritual purity – of freedom from human contamination.

tn Heb “slain [one].”

tn Heb “wadi,” a seasonal watercourse through a valley.
