1 Samuel 23:7-8

7When Saul was told that David went to Keilah, Saul said, “God has delivered him into my hands. He has trapped himself by going into a city which has ⌞a gate with⌟ a double door ⌞held shut by⌟ a bar.”

8So Saul called together all the troops to go to war and blockade Keilah, where David and his men were.
