Numbers 19:2-6

²This is the ordinance of the law which the LORD hath commanded, saying, Speak unto the children of Israel, that they bring thee a red heifer without spot, wherein is no blemish, and upon which never came yoke:

³And ye shall give her unto Eleazar the priest, that he may bring her forth without the camp, and one shall slay her before his face:

⁴And Eleazar the priest shall take of her blood with his finger, and sprinkle of her blood directly before the tabernacle of the congregation seven times:

⁵And one shall burn the heifer in his sight; her skin, and her flesh, and her blood, with her dung, shall he burn:

⁶And the priest shall take cedar wood, and hyssop, and scarlet, and cast it into the midst of the burning of the heifer.
