Judges 13:7

But he said unto me, Behold, thou shalt conceive, and bear a son; and now drink no wine nor strong drink, neither eat any unclean thing: for the child shall be a Nazarite to God from the womb to the day of his death.

In Jeremiah 35:6, the Rechabites also abstain from wine as a family command, paralleling the Nazirite vow given for Samson.
