Names of God Bible

⁴ As long as they are Nazirites, they must never eat anything that comes from a grapevine, not even grape seeds or skins.

⁵ “As long as they are under the Nazirite vow, no razor may touch their heads. During the entire time that they are dedicated to Yahweh as Nazirites, they will be holy. They must let their hair grow long. ⁶ While they are dedicated to Yahweh as Nazirites, they must never go near a dead body.
