'Sledges' in the Bible

He also brought out the people who were there, and put them to [work with] the saws and sharp iron instruments and iron axes, and made them work at the brickkiln. And he did this to all the Ammonite cities. Then David and all the men returned to Jerusalem.

Araunah said to David, “My lord the king may take whatever he wants and offer it. Here are the oxen for a burnt offering and the threshing sledges and ox yokes for the wood.

Ornan said to David, “Take it! My lord the king may do whatever he wants. See, I give the oxen for the burnt offerings, the threshing sledges for the wood, and the wheat for the grain offering—I give it all.”

The Lord says:I will not relent from punishing Damascusfor three crimes, even four,because they threshed Gilead with iron sledges.
