Judges 16:7-9

New International Version - UK

⁷ Samson answered her, ‘If anyone ties me with seven fresh bow-strings that have not been dried, I’ll become as weak as any other man.’

⁸ Then the rulers of the Philistines brought her seven fresh bow-strings that had not been dried, and she tied him with them. ⁹ With men hidden in the room, she called to him, ‘Samson, the Philistines are upon you!’ But he snapped the bow-strings as easily as a piece of string snaps when it comes close to a flame. So the secret of his strength was not discovered.
