and separate himself to the LORD for the days of his separation and bring a male lamb a year old for a guilt offering. But the previous period shall be void, because his separation was defiled.
The days of their vow that were completed before their defilement no longer count. They must rededicate themselves to the LORD as a Nazirite for the full term of their vow, and each must bring a one-year-old male lamb for a guilt offering.

What does Numbers 6:12 mean?

John Gill's Exposition of the Bible
Numbers 6:12

And he shall consecrate unto the Lord the days of his
separation
He was to begin his account again, from the time of his shaving his head, and devote as many days to the service of the Lord as what he had vowed before:

and shall bring a lamb of the first year for a trespass offering;
we see how much trouble and expense were brought by a single act of pollution, and that involuntary too; how much more need is there of an atoning sacrifice for the sins of men, even for all of them, and for which only the sacrifice of Christ is sufficient?

but the days that were before shall be lost;
which were before the pollution, how near soever the time of Nazariteship being at an end was, whether his vow was for thirty days, or a hundred, or a whole year; be it what it will, and the pollution happened on the last of those days, all were lost; he was obliged to begin again, and go through the whole time he at first vowed; and this was the case if he drank the least quantity of wine, or shaved ever so little of the hair of his head, or was any ways polluted by the dead; and this severity, as it may seem, was used to make him cautious that he broke not his vow by any means:

because his separation was defiled;
in the case instanced in, by the dead, but it was the same if he broke the law of Nazariteship in any of the other articles of it.
