1 Samuel 14:12-16

ISV(i) 12 The men of the garrison responded to Jonathan and his armor bearer: “Come up and fight us, and we will show you something.”
Jonathan then told his armor bearer, “Follow me, for the LORD has given them into Israel’s control.”
13 Jonathan crawled up on his hands and feet, with his armor bearer following him. The Philistines fell before Jonathan, and his armor bearer who was behind him also killed some. 14 In the initial attack, Jonathan and his armor bearer struck down about twenty men in an area of about half an acre of land. 15 There was terror in the camp, in the field, and among all the people. Even the garrison and the raiders were terrified. The earth shook, and there was even greater terror.
16 Saul’s sentries in Gibeah of Benjamin watched as the camp was in disarray, going this way and that.
