'Threshing sledges' in the Bible

And Gideon will say, For this in Jehovah's giving Zebah and Zalmunna into my band, and I threshed your flesh with thorns of the desert and threshing-sledges.

And he will take the old men of the city, and thorns of the desert, and threshing sledges, and with them he caused the men of Succoth to know.

And he brought out the people that were in it, and he will contend with the saw and with threshing-sledges of iron, and with saws. And David will do thus to all the cities of the sons of Ammon. And David will turn back and all the people, to Jerusalem.

And Ornan will say to David, Take to thee, and my lord the king shall, do the good in his eyes: see, I gave the oxen for burnt-offerings, and the threshing-sledges for woods, and the wheat for a gift; I gave all.

Thus said Jehovah: For three transgressions of Damascus, and for four, I will not turn back for their threshing Gilead with threshing-sledges of iron.
