Judges 15:11-12

11Then three thousand men from Judah went down to the cave in the rock of Etam and said to Samson, “Don’t you realize that the Philistines are rulers over us? What have you done to us?” He answered, “I merely did to them what they did to me.” 12They said to him, “We’ve come to tie you up and hand you over to the Philistines.” Samson said, “Swear to me that you won’t kill me yourselves.”
