Numbers 6:6

All the days that he separateth [himself] unto the Lord
This phrase is repeated at every new article and branch of the law of the Nazarites, of which what follows is the third; showing that each part of it, during that time, was strictly to be observed:

he shall come at no dead body:
not near to any, not even to be in the same place where a dead body lay, nor to touch one, nor to attend the funeral of any, nor be concerned at all about burying the dead; now, as such so defiled were unclean seven days, and during that time might not go into the tabernacle, the Nazarites were strictly cautioned against such pollution, that they might not be detained from the service of God they had devoted themselves unto; see ( Numbers 19:11 Numbers 19:14 Numbers 19:16 ) .
