Numbers 19:3-6

³And ye shall betake her to Eleazar, the priest, that shall offer her, led out of the tents, in the sight of all men.

⁴And he shall dip his finger in the blood thereof, and shall sprinkle seven times against the gates of the tabernacle.

⁵And he shall burn that cow, while all men see; and he shall give as well the skin, and the flesh thereof, as the blood, and the dung, to the burning.

⁶Also the priest shall put cedar wood, and hyssop, and red thread dyed twice, into the fire, that burneth the cow.
