Judges 13:3-5

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.

5For lo, thou shalt conceive, and bear a son, and no razor shall come on his head; for the boy shall be a Nazarite of 1God from the womb; and he shall begin to save Israel out of the hand of the Philistines.
