Judges 16:6-8

New King James Version

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

⁷ And Samson said to her, “If they bind me with seven fresh bowstrings, not yet dried, then I shall become weak, and be like any other man.”

⁸ So the lords of the Philistines brought up to her seven fresh bowstrings, not yet dried, and she bound him with them.
