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 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.

4Now therefore beware, I pray thee, and drink no wine nor strong drink, and eat not any unclean thing:

5for, 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.
