1 Samuel 14:11-13

So both of them showed themselves to the Philistine outpost. “Look!” said the Philistines. “The Hebrews are crawling out of the holes they were hiding in.” The men of the outpost shouted to Jonathan and his armor-bearer, “Come up to us and we’ll teach you a lesson.” So Jonathan said to his armor-bearer, “Climb up after me; the LORD has given them into the hand of Israel.” Jonathan climbed up, using his hands and feet, with his armor-bearer right behind him. The Philistines fell before Jonathan, and his armor-bearer followed and killed behind him.
