Judges 13:2-4

2And there was a certain man of Zoreah, of the family of the Danites, and his name was Manoah. And his wife was barren and did not bear.

3And the Angel of Jehovah appeared to the woman, and said to her, Behold now, thou art barren and bearest not; but thou shalt conceive and bear a son.

4And now beware, I pray thee, and drink not wine nor strong drink, and eat nothing unclean.
