'Stocks' in the Bible

So Pashhur had Jeremiah the prophet beaten and put him in the stocks at the Upper Benjamin Gate in the Lord’s temple.

The next day, when Pashhur released Jeremiah from the stocks, Jeremiah said to him, “The Lord does not call you Pashhur, but Magor-missabib,

‘The Lord has appointed you priest in place of Jehoiada the priest to be the chief officer in the temple of the Lord, responsible for every madman who acts like a prophet. You must confine him in the stocks and an iron collar.
