Judges 14:5-6

5Then Samson went down to Timnah with his father and mother [to arrange the marriage], and they came as far as the vineyards of Timnah; and suddenly, a young lion came roaring toward him.

6The Spirit of the Lord came upon him mightily, and he tore the lion apart as one tears apart a young goat, and he had nothing at all in his hand; but he did not tell his father or mother what he had done.
