Judges 16:8

4 Some time later, Samson fell in love with a woman in the Valley of Sorek, whose name was Delilah.

5 The lords of the Philistines went to her and said, “Entice him and find out the source of his great strength and how we can overpower him to tie him up and subdue him. Then each one of us will give you eleven hundred shekels of silver.”

6 So Delilah said to Samson, “Please tell me the source of your great strength and how you can be tied up and subdued.”

7 Samson told her, “If they tie me up with seven fresh bowstrings that have not been dried, I will become as weak as any other man.”

8 So the lords of the Philistines brought her seven fresh bowstrings that had not been dried, and she tied him up with them.

9 While the men were hidden in her room, she called out, “Samson, the Philistines are here!” But he snapped the bowstrings like a strand of yarn seared by a flame. So the source of his strength remained unknown.

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.
