Judges 16:5, 18-21

The rulers of the Philistines went to her and said, “Entice Samson to tell you what makes him so strong and how he can be overpowered and tied up securely. Then each of us will give you 1,100 pieces of silver.”

Delilah realized he had finally told her the truth, so she sent for the Philistine rulers. “Come back one more time,” she said, “for he has finally told me his secret.” So the Philistine rulers returned with the money in their hands. Delilah lulled Samson to sleep with his head in her lap, and then she called in a man to shave off the seven locks of his hair. In this way she began to bring him down, and his strength left him. Then she cried out, “Samson! The Philistines have come to capture you!” When he woke up, he thought, “I will do as before and shake myself free.” But he didn’t realize the LORD had left him. So the Philistines captured him and gouged out his eyes. They took him to Gaza, where he was bound with bronze chains and forced to grind grain in the prison.
