Judges 16:8-13

8So the lords of the Philistines brought her seven fresh bowstrings that had not been dried, and she tied him up with them. 9While 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.

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

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

12So 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.

13Then 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.1”
