Judges 13:1-6

1 And the children of Israel did evil again in the sight of the LORD, and the LORD delivered them into the hand of the Philistines forty years.
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 unto the woman and said unto her, "Behold now, thou art barren and bearest not; but thou shalt conceive and bear a son.
4 Now therefore beware, I pray thee, and drink not wine nor strong drink, and eat not any unclean thing.
5 For, lo, thou shalt conceive and bear a son; and no razor shall come on his head, for the child shall be a Nazirite unto 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 unto me, and his countenance was like the countenance of an angel of God, very fearsome; but I asked him not from whence he was, neither told he me his name.
