Judges 13:3

1 Again the Israelites did evil in the sight of the LORD, so He delivered them into the hand of the Philistines for forty years.

2 Now there was a man from Zorah named Manoah, from the clan of the Danites, whose wife was barren and had no children.

3 The angel of the LORD appeared to the woman and said to her, “It is true that you are barren and have no children; but you will conceive and give birth to a son.

4 Now please be careful not to drink wine or strong drink, and not to eat anything unclean.

5 For behold, you will conceive and give birth to a son. And no razor shall come over his head, because the boy will be a Nazirite to God from the womb, and he will begin the deliverance of Israel from the hand of the Philistines.”

6 So the woman went and told her husband, “A man of God came to me. His appearance was like the angel of God, exceedingly awesome. I did not ask him where he came from, and he did not tell me his name.

7 But he said to me, ‘Behold, you will conceive and give birth to a son. Now, therefore, do not drink wine or strong drink, and do not eat anything unclean, because the boy will be a Nazirite to God from the womb until the day of his death.’”
