Judges 16:14

10 Then Delilah said to Samson, “You have mocked me and lied to me! Now please tell me how you can be tied up.”

11 He replied, “If they tie me up with new ropes that have never been used, I will become as weak as any other man.”

12 So Delilah took new ropes, tied him up with them, and called out, “Samson, the Philistines are here!” But while the men were hidden in her room, he snapped the ropes off his arms like they were threads.

13 Then Delilah said to Samson, “You have mocked me and lied to me all along! Tell me how you can be tied up.” He told her, “If you weave the seven braids of my head into the web of a loom and tighten it with a pin, I will become as weak as any other man.”

14 So while he slept, Delilah took the seven braids of his hair and wove them into the web. Then she tightened it with a pin and called to him, “Samson, the Philistines are here!” But he awoke from his sleep and pulled out the pin with the loom and the web.

15 “How can you say, ‘I love you,’” she asked, “when your heart is not with me? This is the third time you have mocked me and failed to reveal to me the source of your great strength!”

16 Finally, after she had pressed him daily with her words and pleaded until he was sick to death,

17 Samson told her all that was in his heart: “My hair has never been cut, because I have been a Nazirite to God from my mother’s womb. If I am shaved, my strength will leave me, and I will become as weak as any other man.”

18 When Delilah realized that he had revealed to her all that was in his heart, she sent this message to the lords of the Philistines: “Come up once more, for he has revealed to me all that is in his heart.” Then the lords of the Philistines came to her, bringing the money in their hands.
