Numbers 6:8-10

Amplified Bible

⁸ All the time of his separation he is holy to the Lord.

⁹ ‘If a man dies very suddenly beside him, and he defiles his dedicated head, then he shall shave his head on the day that he becomes [ceremonially] clean; he shall shave it on the seventh day [the end of the purification period]. ¹⁰ On the eighth day he shall bring two turtledoves or two young pigeons to the priest, to the doorway of the Tent of Meeting (tabernacle).
