Judges 13:2-5

2And 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. 3And the angel of Yhwh appeared unto the woman, and said unto her, Behold now, thou art barren, and bearest not: but thou shalt conceive, and bear a son. 4Now therefore beware, I pray thee, and drink not wine nor strong drink, and eat not any unclean thing: 5For, 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.
