'Pillar' in the Bible

All the men of Shechem and all of Beth-millo assembled together, and they went and made Abimelech king, by the oak (terebinth) of the pillar (memorial stone) at Shechem.

But when the [signal] cloud began to rise out of the city in a column of smoke, the Benjamites looked behind them; and behold, the entire city went up in smoke to heaven.
