TSK · Numbers 6:9

The Nazirite shall shave the head of his separation at the door of the Tent of Meeting, and shall take the hair of the head of his separation, and put it on the fire which is under the sacrifice of peace offerings.

In the day that he goes into the sanctuary, into the inner court, to minister in the sanctuary, he shall offer his sin offering, says the Lord Yahweh.

Therefore do what we tell you. We have four men who have taken a vow.
