Judges 14:4, 19

But his father and mother did not know that it was of the LORD—that He was seeking an occasion to move against the Philistines. For at that time the Philistines had dominion over Israel.

Then the Spirit of the LORD came upon him mightily, and he went down to Ashkelon and killed thirty of their men, took their apparel, and gave the changes of clothing to those who had explained the riddle. So his anger was aroused, and he went back up to his father’s house.
