Judges 13:2-7

2 And there was a certain man of Zorah, of the family of the Danites, whose name was Manoah; and his wife was barren, and bore not.

3 And the angel of the LORD appeared to the woman, and said to her, Behold now, you are barren, and bore not: but you shall conceive, and bear a son.

4 Now therefore beware, I pray you, and drink not wine nor strong drink, and eat not any unclean thing:

5 For, see, you shall conceive, and bear a son; and no razor shall come on his head: for the child shall be a Nazarite to God from the womb: and he shall begin to deliver Israel out of the hand of the Philistines.

6 Then the woman came and told her husband, saying, A man of God came to me, and his countenance was like the countenance of an angel of God, very terrible: but I asked him not from where he was, neither told he me his name:

7 But he said to me, Behold, you shall conceive, and bear a son; and now drink no wine nor strong drink, neither eat any unclean thing: for the child shall be a Nazarite to God from the womb to the day of his death.
