Judges 13 1-5
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 bare 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 Nazarite unto God from the womb: and he shall begin to deliver Israel out of the hand of the Philistines.
