Judges 15:6-8

6Then the Philistines said, “Who did this?” And they were told, “Samson, the son-in-law of the Timnite, because he took Samson’s wife and gave her to his [chief] companion [at the wedding feast].” So the Philistines came up and burned her and her father with fire.

7Samson said to them, “If this is the way you act, be certain that I will take revenge on you, and [only] after that I will stop.”

8Then he struck them without mercy, a great slaughter; and he went down and lived in the cleft of the rock of Etam.
