Numbers 6
3 Ref He is to keep himself from wine and strong drink, and take no mixed wine or strong drink or any drink made from grapes, or any grapes, green or dry.
4 Ref All the time he is separate he may take nothing made from the grape-vine, from its seeds to its skin.
5 Ref All the time he is under his oath let no blade come near his head; till the days while he is separate are ended he is holy and his hair may not be cut.
6 Ref All the time he is separate he may not come near any dead body.
7 Ref He may not make himself unclean for his father or his mother, his sister or his brother, if death comes to them; because he is under an oath to keep himself separate for God.
