Judges 16:17-19

17So he told her all that was in his heart and said to her, “A razor has never come on my head, for I have been a 1Nazirite to God from my mother’s womb. If I am shaved, then my strength will leave me and I will become weak and be like any other man.”

18When Delilah saw that he had told her all that was in his heart, she sent and called the lords of the Philistines, saying, “Come up once more, for he has told me all that is in his heart.” Then the lords of the Philistines came up to her and brought the money in their hands. 19She made him sleep on her knees, and called for a man and had him shave off the seven locks of his 2hair. Then she began to afflict him, and his strength left him.
