Judges 16:16-20

She kept bothering Samson about his secret day after day until he felt he was going to die! So he told her everything. He said, “I have never had my hair cut, because I have been set apart to God as a Nazirite since I was born. If someone shaved my head, I would lose my strength and be as weak as any other man.” When Delilah saw that he had told her everything sincerely, she sent a message to the Philistine rulers. She said, “Come back one more time, because he has told me everything.” So the Philistine rulers came back to Delilah and brought the silver with them. Delilah got Samson to sleep, lying in her lap. Then she called in a man to shave off the seven braids of Samson’s hair. In this way she began to make him weak, and his strength left him. Then she said, “Samson, the Philistines are here!” He woke up and thought, “I’ll leave as I did before and shake myself free.” But he did not know that the LORD had left him.
