⁴ And the zekenim of that town shall bring down the heifer unto a wadi with running water, which is neither plowed nor sown, and shall break the heifer’s neck there in the wadi;

⁵ And the kohanim the Bnei Levi shall come near; for them Hashem Eloheicha hath chosen to minister unto Him, and to bless in the Shem of Hashem; and by their word shall every controversy and every assault be tried;
