Parallel
Judges 16:9
Jewish Publication Society 1917 · Berean Standard Bible
Now she had liers-in-wait abiding in the inner chamber. And she said unto him: ‘The Philistines are upon thee, Samson.’ And he broke the bowstrings as a string of tow is broken when it toucheth 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.
