Judges 13:6-16

6 Then the woman came and told her husband, "A man of God came to me, and his countenance was like the countenance of the angel of God, very terrible; I did not ask him whence he was, and he did not tell me his name;
7 but he said to me, 'Behold, you shall conceive and bear a son; so then drink no wine or strong drink, and eat nothing unclean, for the boy shall be a Nazirite to God from birth to the day of his death.'"
8 Then Mano'ah entreated the LORD, and said, "O, LORD, I pray thee, let the man of God whom thou didst send come again to us, and teach us what we are to do with the boy that will be born."
9 And God listened to the voice of Mano'ah, and the angel of God came again to the woman as she sat in the field; but Mano'ah her husband was not with her.
10 And the woman ran in haste and told her husband, "Behold, the man who came to me the other day has appeared to me."
11 And Mano'ah arose and went after his wife, and came to the man and said to him, "Are you the man who spoke to this woman?" And he said, "I am."
12 And Mano'ah said, "Now when your words come true, what is to be the boy's manner of life, and what is he to do?"
13 And the angel of the LORD said to Mano'ah, "Of all that I said to the woman let her beware.
14 She may not eat of anything that comes from the vine, neither let her drink wine or strong drink, or eat any unclean thing; all that I commanded her let her observe."
15 Mano'ah said to the angel of the LORD, "Pray, let us detain you, and prepare a kid for you."
16 And the angel of the LORD said to Mano'ah, "If you detain me, I will not eat of your food; but if you make ready a burnt offering, then offer it to the LORD." (For Mano'ah did not know that he was the angel of the LORD.)
