Judges 16:15-17

15Then she said to him, How canst thou say, I love thee, when thy heart is not with me? these three times hast thou mocked me, and hast not told me in what is thy great strength.

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

17and he told her all his heart, and said to her, There has not come a razor upon my head; for I am a Nazarite of 1God from my mother's womb; if I should be shaven, then my strength would go from me, and I should be weak, and be like all mankind.
