Shofetim 16:7-9

Orthodox Jewish Bible

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.

⁹ Now there were men lying in wait, abiding with her in the cheder. And she said unto him, The Pelishtim be upon thee, Shimshon. And he broke the bowstrings, as a piece of thread is broken when it toucheth the eish. So his ko’ach was not known.
