Judges 13:2-4

2Now there was a certain man from Zorah, from a Danite clan, whose name was Manoah. His wife was barren and bore no children.

3Then the angel of Adonai appeared to the woman and said to her, “Behold now, you are barren and have not borne children, but you will conceive and bear a son.

4Now therefore be careful not to drink wine or strong drink, or eat any unclean thing.
