Numbers 19:1-6

And the LORD spake unto Moses and unto Aaron, saying, This {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: And 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: And 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: And {one} shall burn the heifer in his sight; her skin, and her flesh, and her blood, with her dung, shall he burn: And the priest shall take cedar wood, and hyssop, and scarlet, and cast {it} into the midst of the burning of the heifer.
