Judges 16:7-9

King James Version

⁷ And Samson said unto her, If they bind me with seven green withs that were never dried, then shall I be weak, and be as another man.

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

⁹ Now there were men lying in wait, abiding with her in the chamber. And she said unto him, The Philistines be upon thee, Samson. And he brake the withs, as a thread of tow is broken when it toucheth the fire. So his strength was not known.
