Judges 16:7-9

7Samson said to her, “If they bind me with seven fresh cords that have never been dried, then I would be weak and be like any other man.”

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.
