Judges 16:15-17

15She said to him, “How can you say, ‘I love you,’ when you will not share your secret with me? Three times you have deceived me and have not told me what makes you so strong.”

16She nagged him every day and pressured him until he was sick to death of it.

17Finally he told her his secret. He said to her, “My hair has never been cut, for I have been dedicated to God from the time I was conceived. If my head were shaved, my strength would leave me; I would become weak, and be just like all other men.”
