'Pillar' in the Bible

All the men of Shechem assembled themselves together, and all the house of Millo, and went and made Abimelech king, by the oak of the pillar that was in Shechem.

But when the cloud began to arise up out of the city in a pillar of smoke, the Benjamites looked behind them; and behold, the whole of the city went up in smoke to the sky.
