Judges 16:15-17

15Then she said to him, “How can you say, ‘I love you,’ when your heart is not with me? You have mocked me these three times, and have not told me where your great strength lies.”

16And it came to pass, when she pestered him daily with her words and pressed him, so that his soul was vexed to death,

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