Judges 16:7-9

7Samson said to her, “If they bind me with seven fresh cords that have not been dried, then I will become weak and be like any other man.” 8Then the lords of the Philistines brought up to her seven fresh cords that had not been dried, and she bound him with them. 9Now she had men lying in wait in an inner room. And she said to him, “The Philistines are upon you, Samson!” But he snapped the cords as a string of tow snaps when it 1touches fire. So his strength was not discovered.
