Shamgar son of Anath שמגר בן ענת

"And after him came Shamgar son of Anath, and he struck down six hundred Philistines with an ox-goad; and he too delivered Israel."

That is the whole text. No oppression, no term of office, no rest for the land — none of the usual cycle of the book of Judges. He is not even called a judge outright: it says he "delivered."

What matters here is the tool. An ox-goad is a long staff with an iron tip, used to drive a bullock in harness; it is not a weapon but a ploughman's implement. The book of Samuel explains why the Israelites had no real weapons: the Philistines allowed them no smiths, "lest the Hebrews make a sword or a spear," and they had to go to the Philistines even to sharpen their tools.

He is mentioned a second time in Deborah's song, where his name serves as a marker of the period: "in the days of Shamgar son of Anath, in the days of Jael, the roads were deserted, and travellers went by roundabout paths."

The years here are computed by adding up the terms given in the book of Judges itself, counting from the death of Joshua; they are not stated as such in the source.
