Judges 16:9-12

With men hidden in the room, she called to him, “Samson, the Philistines are upon you!” But he snapped the bowstrings as easily as a piece of string snaps when it comes close to a flame. So the secret of his strength was not discovered. Then Delilah said to Samson, “You have made a fool of me; you lied to me. Come now, tell me how you can be tied.” He said, “If anyone ties me securely with new ropes that have never been used, I’ll become as weak as any other man.” So Delilah took new ropes and tied him with them. Then, with men hidden in the room, she called to him, “Samson, the Philistines are upon you!” But he snapped the ropes off his arms as if they were threads.
