Isaiah 41:15

Behold, I have made thee as new saw-shaped threshing wheels of a waggon; and thou shalt thresh the mountains, and beat the hills to powder, and make [them] as chaff:

Behold, I will make thee a new sharp threshing instrument having teeth: thou shalt thresh the mountains, and beat them small, and shalt make the hills as chaff.

Behold, I have made you into a new sharp threshing instrument with teeth. You will thresh the mountains, and beat them small, and will make the hills like chaff.
