Leviticus 8:34-36

Young's Literal Translation

³⁴ as he hath done on this day, Jehovah hath commanded to do, to make atonement for you;

³⁵ and at the opening of the tent of meeting ye abide, by day and by night seven days, and ye have kept the charge of Jehovah, and die not, for so I have been commanded.'

³⁶ And Aaron doth -- his sons also -- all the things which Jehovah hath commanded by the hand of Moses.
