Judges 16:8-13

8So the Philistine lords brought up to her seven fresh cords that had never been dried, and she bound him with them,

9while an ambush was waiting in an inner room. “The Philistines are upon you, Samson!” she said to him. But he broke the cords just as a strand of straw snaps when it touches fire. So his strength remained unknown.

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.

13So Delilah said to Samson, “Up to now you’ve mocked me and told me lies! Tell me how you can be bound!” He told her, “If you weave the seven locks of my head with the web of a loom.”
