Judges 16:7-9

Amplified Bible, Classic Edition

⁷ And Samson said to her, If they bind me with seven fresh, strong gutstrings, still moist, then shall I be weak and be like any other man.

⁸ Then the Philistine lords brought to her seven fresh, strong bowstrings, still moist, and she bound him with them.

⁹ Now she had men lying in wait in an inner room. And she said to him, The Philistines are upon you, Samson! And he broke the bowstrings as a string of tow breaks when it touches the fire. So the secret of his strength was not known.
