Judges 13:3-5

And the angel of Jehovah appeared unto the woman, and said unto her, Behold now, thou art barren, and bearest not; but thou shalt conceive, and bear a son. Now therefore beware, I pray thee, and drink no wine nor strong drink, and eat not any unclean thing: for, lo, thou shalt conceive, and bear a son; and no razor shall come upon his head; for the child shall be a Nazirite unto God from the womb: and he shall begin to save Israel out of the hand of the Philistines.
