Judges 16:10-12

10Delilah said to Samson, “Oh, you deceived me! You lied to me! Now tell me please, how you can be bound?”

11He told her, “If they only bind me with new ropes never used for work, then I will be weak and be like any other man.”

12So Delilah took new ropes, tied him up with them and said to him, “The Philistines are upon you, Samson!” Yet while the ambush was waiting in the inner room, he snapped them from his arms like a thread.
