Numbers 19:2-6

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

3And ye shall give her to Eleazar the priest, that he may bring her forth outside 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.
