Thematic Bible: Samson's mother forbidden to drink

Now therefore beware, I pray thee, and drink no wine nor strong drink, and do not eat any unclean thing, for, lo, thou shall conceive, and bear a son. And no razor shall come upon his head, for the child shall be a Nazirite to God from the womb. And he shall begin to save Israel out of the hand of the Philistines.
