Numbers 6:4

all the days of his vow: he shall eat no one of all the things that come from the vine, wine from the grape-stones to the husk,

All the days of his separation shall he eat nothing that is made of the vine tree, from the kernels even to the husk.

All the days of his separation he shall eat nothing that is made of the grapevine, from the seeds even to the skins.
