1 Samuel 14:11-13

11And both of them shewed themselves to the garrison of the Philistines; and the Philistines said, Behold, the Hebrews come forth out of the holes where they had hid themselves.

12And the men of the garrison answered Jonathan and his armour-bearer and said, Come up to us, and we will shew you something. And Jonathan said to his armour-bearer, Come up after me; for Jehovah has delivered them into the hand of Israel.

13And Jonathan climbed up upon his hands and upon his feet, and his armour-bearer after him; and they fell before Jonathan; and his armour-bearer slew after him.
