Judges 13:5-8

For behold, you 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 deliver Israel out of the hand of the Philistines.” So the woman came and told her husband, saying, “A Man of God came to me, and His countenance was like the countenance of the Angel of God, very awesome; but I did not ask Him where He was from, and He did not tell me His name. And He said to me, ‘Behold, you shall conceive and bear a son. Now drink no wine or similar drink, nor eat anything unclean, for the child shall be a Nazirite to God from the womb to the day of his death.’ ” Then Manoah prayed to the LORD, and said, “O my Lord, please let the Man of God whom You sent come to us again and teach us what we shall do for the child who will be born.”
