Shofetim 16:6-8

Orthodox Jewish Bible

⁶ And Delilah said to Shimshon, Tell me, now, wherein thy koach gadol lieth, and wherewith thou mightest be bound to subdue thee.

⁷ And Shimshon said unto her, If they bind me with shivah fresh bowstrings that were never dried, then shall I be weak, and be as any adam.

⁸ Then the rulers of the Pelishtim brought up to her shivah fresh bowstrings which had not been dried, and she bound him with them.
