Parallel
Judges 16:9
World English Bible British Edition · Berean Standard Bible
Now she had an ambush waiting in the inner room. She said to him, “The Philistines are on you, Samson!” He broke the cords as a flax thread is broken when it touches the fire. So his strength was not known.
While the men were hidden in her room, she called out, “Samson, the Philistines are here!” But he snapped the bowstrings like a strand of yarn seared by a flame. So the source of his strength remained unknown.
