16:6 So Delilah said to Samson, “Tell me what makes you so strong and how you can be subdued and humiliated.”

Judges 16:10

16:10 Delilah said to Samson, “Look, you deceived me and told me lies! Now tell me how you can be subdued.”

Judges 16:15-20

16:15 She said to him, “How can you say, ‘I love you,’ when you will not share your secret with me? Three times you have deceived me and have not told me what makes you so strong.” 16:16 She nagged him every day and pressured him until he was sick to death of it. 16:17 Finally he told her his secret. He said to her, “My hair has never been cut, for I have been dedicated to God from the time I was conceived. If my head were shaved, my strength would leave me; I would become weak, and be just like all other men.” 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.
