1 Samuel 14:11-13

11When both of them revealed themselves to the garrison of the Philistines, the Philistines said, “Look, the Hebrews are coming out of the holes where they have hidden themselves.”

12So the men of the garrison responded to Jonathan and his armor bearer, “Come up to us and we will tell you something.” Jonathan said to his armor bearer, “Climb up after me, for the Lord has given them into the hands of Israel.”

13Then Jonathan climbed up on his hands and feet, his armor bearer following after him. The enemy fell before Jonathan [in combat], and his armor bearer killed some of them after him.
