Juízes 16:9

9 With men hidden in the room, she called to him, "Samson, the Philistines are upon you!" But he snapped the bowstrings as easily as a piece of string snaps when it comes close to a flame. So the secret of his strength was not discovered.

9 Now she had men waiting secretly in the inner room; and she said to him, The Philistines are on you, Samson. And the cords were broken by him as a twist of thread is broken when touched by a flame. So the secret of his strength did not come to light.
