³  You shall give her to Eleazar the priest, and he shall bring her forth outside of the camp, and one shall kill her before his face:

⁴  and Eleazar the priest shall take of her blood with his finger, and sprinkle her blood toward the front of the tent of meeting seven times.

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

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