There shall no razor come upon his head. — The hair was to be suffered to grow in all its luxuriance during the days of the Nazirite vow. The meaning may be illustrated by reference to Leviticus 25:4-5; Leviticus 25:11, where it is prescribed that in the seventh year the vine was not to be pruned, and that the grapes of “the undressed vine” (literally, the grapes of the Nazirite) should not be gathered.
