Judges 13:3; Judges 13:7

3 Then the angel of the LORD appeared to the woman and said to her, "Behold now, you are barren and have borne no children, but you shall conceive and give birth to a son.

7 "But he said to me, 'Behold, you shall conceive and give birth to a son, and now you shall not drink wine or strong drink nor eat any unclean thing, for the boy shall be a Nazirite to God from the womb to the day of his death.' "
