Then 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:
Ye have herde howe it was sayd vnto the of ye olde tyme: Thou shalt not kyll. For whoso ever kylleth shall be in daunger of iudgemet.Matthew 5:21 TYN
And the priest shall command that one of the birds be killed in an earthen vessel over running water:Leviticus 14:5 KJV
And the priest shall go forth out of the camp; and the priest shall look, and, behold, if the plague of leprosy be healed in the leper;Leviticus 14:3 KJV
