Numbers 6:5

“All the days of the vow of his separation, etc.] Be the time he has vowed to be a Nazarite a week, a, month, or more, even a thousand days, but not less than thirty, as Ben Gersom observes: there shall no razor come upon his head; he might not shave his beard, nor cut off his locks, and shave his head, nor cut short his locks with a pair of scissors, nor any with anything by which the hair may be removed, as Ben Gersom; nor pluck off his hair with his hands, as Maimonides says f67; but let it grow as long as it would during the time of his separation, which is expressed in the latter part of the verse: until the days be fulfilled, in the which he separateth [himself] unto the Lord; to his…”

Holy - That is, wholly consecrated to God and his service, whereby he shews that inward holiness was the great thing which God required and valued in these, and consequently in other rites and ceremonies.…”
