21 Jehovah went on to say to Moses: “Talk to the priests, Aaron’s sons, and say to them, ‘No one should defile himself for a dead person* among his people.+
9 But if someone should suddenly die alongside him+ and he defiles the hair symbolizing his separation to God,* he must shave his head+ on the day he establishes his purification. He should shave it on the seventh day.
6 Now there were men who had become unclean by touching a dead body,*+ so that they were not able to prepare the Passover sacrifice on that day. So those men presented themselves before Moses and Aaron on that day+
19 And you should camp outside the camp seven days. Every one of you who has killed someone* and every one of you who has touched someone slain+ should purify himself+ on the third day and on the seventh day, you and your captives.
