Judges 13:5-8

You will become pregnant and give birth to a son, and his hair must never be cut. For he will be dedicated to God as a Nazirite from birth. He will begin to rescue Israel from the Philistines.” The woman ran and told her husband, “A man of God appeared to me! He looked like one of God’s angels, terrifying to see. I didn’t ask where he was from, and he didn’t tell me his name. But he told me, ‘You will become pregnant and give birth to a son. You must not drink wine or any other alcoholic drink nor eat any forbidden food. For your son will be dedicated to God as a Nazirite from the moment of his birth until the day of his death.’” Then Manoah prayed to the LORD, saying, “Lord, please let the man of God come back to us again and give us more instructions about this son who is to be born.”
