'Unclean' in the Bible

And, now, take heed, I pray thee, and do not drink wine, and strong drink, and do not eat any unclean thing,

and he saith to me, Lo, thou art pregnant, and bearing a son, and now do not drink wine and strong drink, and do not eat any unclean thing, for a Nazarite to God is the youth from the womb till the day of his death.'

of anything which cometh out from the wine-vine she doth not eat, and wine and strong drink she doth not drink, and any unclean thing she doth not eat; all that I have commanded her she doth observe.'
