Judges 13:6-7

Then the woman came in, and said to her husband, A man came to me, and his form was like the form of a god, causing great fear; I put no question to him about where he came from, and he did not give me his name; But he said to me, You are with child and will give birth to a son; and now do not take any wine or strong drink or let anything unclean be your food; for the child will be separate to God from his birth to the day of his death.
