Numbers 6
9 Ref If death comes suddenly to a man at his side, so that he becomes unclean, let his hair be cut off on the day when he is made clean, on the seventh day.
10 Ref And on the eighth day let him take to the priest, at the door of the Tent of meeting, two doves or two young pigeons;
11 Ref And the priest will give one for a sin-offering and the other for a burned offering to take away the sin which came on him on account of the dead, and he will make his head holy that same day.
