Judges 15:11-12

11Then 3,000 men of Judah went down to the cleft of the rock of Etam, and said to Samson, “Do you not know that the Philistines are rulers over us? What then is this that you have done to us?” And he said to them, “As they did to me, so have I done to them.” 12And they said to him, “We have come down to bind you, that we may give you into the hands of the Philistines.” And Samson said to them, “Swear to me that you will not attack me yourselves.”
