Judges 15:6-8

6Then the Philistines said, "Who has done this?" And they said, "Samson, the son-in-law of the Timnite, because he has taken his wife and given her to his companion." And the Philistines came up and burned her and her father with fire.

7And Samson said to them, "If this is what you do, I swear I will be avenged on you, and after that I will quit."

8And he struck them hip and thigh with a great blow, and he went down and stayed in the cleft of the rock of Etam.
