Devarim 21:5-7

Orthodox Jewish Bible

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;

⁶ And all the zekenim of that town, that are next unto the slain man, shall wash their hands over the heifer whose neck was broken in the valley;

⁷ And they shall answer and say, Yadeinu (our hands) are not guilty of shefach dahm (shedding blood), neither have our eyes seen it.
