Judges 13:2-5

2 And 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.

3 And the angel of the LORD appeared to the woman, and said to her, Behold now, you are barren, and bore not: but you shall conceive, and bear a son.

4 Now therefore beware, I pray you, and drink not wine nor strong drink, and eat not any unclean thing:

5 For, see, you shall 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 out of the hand of the Philistines.
