'Pillar' in the Bible

And all the townsmen of Shechem and all Beth-millo came together and went and made Abimelech their king, by the oak of the pillar in Shechem.

Now the sign fixed between the men of Israel and those making the surprise attack was that when they made a pillar of smoke go up from the town,

Then the sign went up out of the town in the pillar of smoke, and the Benjamites, turning back, saw all the town going up in smoke to heaven.
