Judges 16:8

6Delilah said to Samson, “Please tell me where your great strength lies, and what you might be bound to afflict you.”

7Samson said to her, “If they bind me with seven green cords that were never dried, then shall I become weak, and be as another man.”

8Then the lords of the Philistines brought up to her seven green cords which had not been dried, and she bound him with them.

9Now she had an ambush waiting in the inner room. She said to him, “The Philistines are on you, Samson!” He broke the cords as a flax thread is broken when it touches the fire. So his strength was not known.

10Delilah said to Samson, “Behold, you have mocked me, and told me lies. Now please tell me how you might be bound.”
