Judges 16:10-12

10Then Delilah said to Samson, “You have mocked me and told me lies! Won’t you please tell me how you can be tied up?”

11He told her, “If they tie me up with new ropes that have never been used, I will become weak and be like any other man.”

12Delilah took new ropes, tied him up with them, and shouted, “Samson, the Philistines are here!” But while the men in ambush were waiting in her room, he snapped the ropes off his arms like a thread.
