Judges 14:6

14:6 The Lord’s spirit empowered him and he tore the lion in two with his bare hands as easily as one would tear a young goat. But he did not tell his father or mother what he had done.

Judges 16:9

16:9 They hid in the bedroom and then she said to him, “The Philistines are here, Samson!” He snapped the bowstrings as easily as a thread of yarn snaps when it is put close to fire. The secret of his strength was not discovered.
