Judges 14:4, 19

But his father and his mother knew not that it was of Jehovah; for he sought an occasion against the Philistines. Now at that time the Philistines had rule over Israel.

And the Spirit of Jehovah came mightily upon him, and he went down to Ashkelon, and smote thirty men of them, and took their spoil, and gave the changes of raiment unto them that declared the riddle. And his anger was kindled, and he went up to his father’s house.
