Judges 16:15-17

And 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 you have not told me where your great strength lies.” And when she pressed him hard with her words day after day, and urged him, his soul was vexed to death. And he told her all his heart, and said to her, “A razor has never come upon my head, for I have been a Nazirite to God from my mother’s womb. If my head is shaved, then my strength will leave me, and I shall become weak and be like any other man.”
