And after he is cleansed, they shall reckon unto him seven days.
Numbers 6:10-21
10
'Then on the eighth day he shall bring two turtledoves or two young pigeons to the priest, to the doorway of the tent of meeting.
11
'The priest shall offer one for a sin offering and [the] other for a burnt offering, and make atonement for him concerning his sin because of the [dead] person. And that same day he shall consecrate his head,
12
and shall dedicate to the LORD his days as a Nazirite, and shall bring a male lamb a year old for a guilt offering; but the former days will be void because his separation was defiled.
13
'Now this is the law of the Nazirite when the days of his separation are fulfilled, he shall bring the offering to the doorway of the tent of meeting.
14
'He shall present his offering to the LORD: one male lamb a year old without defect for a burnt offering and one ewe-lamb a year old without defect for a sin offering and one ram without defect for a peace offering,
15
and a basket of unleavened cakes of fine flour mixed with oil and unleavened wafers spread with oil, along with their grain offering and their drink offering.
16
'Then the priest shall present [them] before the LORD and shall offer his sin offering and his burnt offering.
17
'He shall also offer the ram for a sacrifice of peace offerings to the LORD, together with the basket of unleavened cakes; the priest shall likewise offer its grain offering and its drink offering.
18
'The Nazirite shall then shave his dedicated head [of hair] at the doorway of the tent of meeting, and take the dedicated hair of his head and put [it] on the fire which is under the sacrifice of peace offerings.
19
'The priest shall take the ram's shoulder [when it has been] boiled, and one unleavened cake out of the basket and one unleavened wafer, and shall put [them] on the hands of the Nazirite after he has shaved his dedicated [hair].
20
'Then the priest shall wave them for a wave offering before the LORD. It is holy for the priest, together with the breast offered by waving and the thigh offered by lifting up; and afterward the Nazirite may drink wine.'
21
"This is the law of the Nazirite who vows his offering to the LORD according to his separation, in addition to what [else] he can afford; according to his vow which he takes, so he shall do according to the law of his separation."
Numbers 19:11-13
11
'The one who touches the corpse of any person shall be unclean for seven days.
12
'That one shall purify himself from uncleanness with the water on the third day and on the seventh day, [and then] he will be clean; but if he does not purify himself on the third day and on the seventh day, he will not be clean.
13
'Anyone who touches a corpse, the body of a man who has died, and does not purify himself, defiles the tabernacle of the LORD; and that person shall be cut off from Israel. Because the water for impurity was not sprinkled on him, he shall be unclean; his uncleanness is still on him.
Hebrews 9:13
For if the blood of goats and bulls and the ashes of a heifer sprinkling those who have been defiled sanctify for the cleansing of the flesh,
Hebrews 9:14
how much more will the blood of Christ, who through the eternal Spirit offered Himself without blemish to God, cleanse your conscience from dead works to serve the living God?
