'Sledges' in the Bible

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.
