Judges 15:6-8

6Then the Philistines said, “Who did this?” And some said, “Samson, the son-in-law of the Timnite, because 1he took his wife and gave her to his companion.” So the Philistines came up and 2burned her and her father to death with fire. 7Then Samson said to them, “If this is how you act, I will certainly take revenge on you, and only after that will I stop.” 8So he struck them 3ruthlessly with a great slaughter; and afterward he went down and lived in the cleft of the rock of Etam.
