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.
Berean Study Bible (BSB) - Isaiah 41:15 >Behold, I will make you into a threshing sledge, new and sharp, with many teeth. You will thresh the mountains and crush them, and reduce the hills to chaff.
