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 bore not.

3And the angel of the LORD appeared to the woman, and said to 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 to God from the womb: and he shall begin to deliver Israel from the hand of the Philistines.
