Judges 13:1; Judges 13:5

1 Again the Israelites did evil in the eyes of the LORD, so the LORD delivered them into the hands of the Philistines for forty years.

5 You will become pregnant and have a son whose head is never to be touched by a razor because the boy is to be a Nazirite, dedicated to God from the womb. He will take the lead in delivering Israel from the hands of the Philistines.”
