Judges 14:5-6

5While his father and mother went down to Timnah, Samson went to the vineyards of Timnah, and behold, a young lion came roaring at him.

6Then the Ruach Adonai came mightily upon him, and he tore him apart as one would have split a young goat—yet he had nothing in his hand. But he did not tell his father or his mother what he had done.
