Numbers 6:4 In-Context

2 "Say to the people of Israel, When either a man or a woman makes a special vow, the vow of a Nazirite, to separate himself to the LORD,
3 he shall separate himself from wine and strong drink; he shall drink no vinegar made from wine or strong drink, and shall not drink any juice of grapes or eat grapes, fresh or dried.
4 All the days of his separation he shall eat nothing that is produced by the grapevine, not even the seeds or the skins.
5 "All the days of his vow of separation no razor shall come upon his head; until the time is completed for which he separates himself to the LORD, he shall be holy; he shall let the locks of hair of his head grow long.
6 "All the days that he separates himself to the LORD he shall not go near a dead body.
