Judges 13:3-5

but the Angel of YAHWEH appeared to her and said, “Look here! You are no longer barren and childless, for you will conceive and give birth to a son. Now be careful not to drink any wine or beer and to eat nothing considered unclean. You will conceive and will give birth to a son. Raise the boy as one dedicated to God from the womb and never cut his hair. He will begin to deliver Israel from Philistine power.”
