Judges 16:15-17

15“How can you say, ‘I love you,’” she said to him, “when your heart is not with me? This is three times you’ve deceived me and not told me where your great strength comes from.”

16Now it came about when she nagged him daily with her speeches and kept bothering him, his soul was annoyed to death.

17So he divulged to her all his heart and said to her, “No razor has ever been upon my head, for I have been a Nazirite to God from my mother’s womb. If I am shaved, then my strength will go from me, and I will be weak and be like any other man.”
