Judges 13:3-5
13:3 The Lord’s angelic messenger appeared to the woman and said to her, “You are infertile and childless, but you will conceive and have a son.
13:4 Now be careful! Do not drink wine or beer, and do not eat any food that will make you ritually unclean.
13:5 Look, you will conceive and have a son. You must never cut his hair, for the child will be dedicated to God from birth. He will begin to deliver Israel from the power of the Philistines.”
