I Samuel 14:11-13

So both of them showed themselves to the garrison of the Philistines. And the Philistines said, “Look, the Hebrews are coming out of the holes where they have hidden.” Then the men of the garrison called to Jonathan and his armorbearer, and said, “Come up to us, and we will show you something.” Jonathan said to his armorbearer, “Come up after me, for the LORD has delivered them into the hand of Israel.” And Jonathan climbed up on his hands and knees with his armorbearer after him; and they fell before Jonathan. And as he came after him, his armorbearer killed them.
