Judges 16:18-21
16:18 When Delilah saw that he had told her his secret, she sent for the rulers of the Philistines, saying, “Come up here again, for he has told me his secret.” So the rulers of the Philistines went up to visit her, bringing the silver in their hands.
16:19 She made him go to sleep on her lap and then called a man in to shave off the seven braids of his hair. She made him vulnerable and his strength left him.
16:20 She said, “The Philistines are here, Samson!” He woke up and thought, “I will do as I did before and shake myself free.” But he did not realize that the Lord had left him.
16:21 The Philistines captured him and gouged out his eyes. They brought him down to Gaza and bound him in bronze chains. He became a grinder in the prison.
