Judges 13:3-5

3Then the angel of Adonai appeared to the woman and said to her, “Behold now, you are barren and have not borne children, but you will conceive and bear a son.

4Now therefore be careful not to drink wine or strong drink, or eat any unclean thing.

5For behold, you will conceive and bear a son. Let no razor come upon his head, for the boy will be a Nazirite to God from the womb. He will begin to deliver Israel from the hand of the Philistines.”
