Judges 14:4, 19

His father and mother did not know that it was from the LORD, for he was seeking an opportunity against the Philistines. At that time the Philistines ruled over Israel.

And the Spirit of the LORD rushed upon him, and he went down to Ashkelon and struck down thirty men of the town and took their spoil and gave the garments to those who had told the riddle. In hot anger he went back to his father’s house.
