Leviticus 14:1-7

1And the LORD spoke to Moses, saying,

2This shall be the law of the leper in the day of his cleansing: He shall be brought to the priest:

3And the priest shall go forth out of the camp; and the priest shall look, and, behold, if the plague of leprosy is healed in the leper;

4Then shall the priest command to take for him that is to be cleansed two birds alive and clean, and cedar wood, and scarlet, and hyssop:1

5And the priest shall command that one of the birds be killed in an earthen vessel over running water:

6As for the living bird, he shall take it, and the cedar wood, and the scarlet, and the hyssop, and shall dip them and the living bird in the blood of the bird that was killed over the running water:

7And he shall sprinkle upon him that is to be cleansed from the leprosy seven times, and shall pronounce him clean, and shall let the living bird loose into the open field.2
