Judges 13:3-5

3The angel of the Lord appeared to the woman and said to her, “Although you are unable to conceive and have no children, you will conceive and give birth to a son.

4Now please be careful not to drink wine or beer, or to eat anything unclean;

5for indeed, you will conceive and give birth to a son. You must never cut his hair, because the boy will be a Nazirite to God from birth, and he will begin to save Israel from the power of the Philistines.”
