Judges 14:5-6

Then Samson went down with his father and mother to Timnah, and they came to the vineyards of Timnah. And behold, a young lion came toward him roaring. Then the Spirit of the LORD rushed upon him, and although he had nothing in his hand, he tore the lion in pieces as one tears a young goat. But he did not tell his father or his mother what he had done.
