3 from wine and strong drink he doth keep separate; vinegar of wine, and vinegar of strong drink he doth not drink, and any juice of grapes he doth not drink, and grapes moist or dry he doth not eat;

4 all days of his separation, of anything which is made of the wine-vine, from kernels even unto husk, he doth not eat.

5 `All days of the vow of his separation a razor doth not pass over his head; till the fulness of the days which he doth separate to Jehovah he is holy; grown up hath the upper part of the hair of his head.

6 `All days of his keeping separate to Jehovah, near a dead person he doth not go;

7 for his father, or for his mother, for his brother, or for his sister -- he is not unclean for them at their death, for the separation of his God [is] on his head;
