In Samuel 1, 13 & 14, there is a fascinating little story about Saul’s son Jonathan. The Philistines are attacking and it is suddenly the case that there are no blacksmiths amongst the Israelites. The Israelites have to go to the Philistines even to get their axes, mattocks and ploughshares sharpened (didn’t anyone think about this ahead of time?). So Saul gathers his more or less weaponless army and hangs around wondering what to do. Jonathan, his son (who does have weapons), goes berserk (or a reasonable facsimile) and attacks the Philistine all by himself except for his faithful armour bearer who tags along. They climb a cliff to get to the Philistine host and fall upon it, killing twenty men right away.
014:011 And both of them discovered themselves unto the garrison of
the Philistines: and the Philistines said, Behold, the Hebrews
come forth out of the holes where they had hid themselves.014:012 And the men of the garrison answered Jonathan and his
armourbearer, and said, Come up to us, and we will shew you a
thing. And Jonathan said unto his armourbearer, Come up after
me: for the LORD hath delivered them into the hand of Israel.014:013 And Jonathan climbed up upon his hands and upon his feet, and
his armourbearer after him: and they fell before Jonathan; and
his armourbearer slew after him.014:014 And that first slaughter, which Jonathan and his armourbearer
made, was about twenty men, within as it were an half acre of
land, which a yoke of oxen might plow.
