Judges 16:16-21

When she pressured him day after day with her words and pleaded with him, he was annoyed to death. Then [finally] he told her everything that was in his heart and said to her, “A razor has never been used on my head, for I have been a Nazirite 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.” Then Delilah realized that he had told her everything in his heart, so she sent and called for the Philistine lords, saying, “Come up this once, because he has told me everything in his heart.” Then the Philistine lords came up to her and brought the money [they had promised] in their hands. She made Samson sleep on her knees, and she called a man and had him shave off the seven braids of his head. Then she began to abuse Samson, and his strength left him. She said, “The Philistines are upon you, Samson!” And he awoke from his sleep and said, “I will go out as I have time after time and shake myself free.” For Samson did not know that the LORD had departed from him. Then the Philistines seized him and gouged out his eyes; and they brought him down to Gaza and bound him with [two] bronze chains; and he was forced to be a grinder [of grain into flour at the mill] in the prison.
