1 Samuel 14:13-15

So Jonathan climbed up, using his hands and feet, and his officer climbed just behind him. Jonathan struck down the Philistines as he went, and his officer killed them as he followed behind him. In that first fight Jonathan and his officer killed about twenty Philistines over a half acre of ground. All the Philistine soldiers panicked—those in the camp and those in the raiding party. The ground itself shook! God had caused the panic.
