'Grinding' in the Bible

The people walked around and gathered it. They ground it on a pair of grinding stones or crushed it in a mortar, then boiled it in a cooking pot and shaped it into cakes. It tasted like a pastry cooked with the finest oil.

I took the sinful calf you had made, burned it up, and crushed it, thoroughly grinding it to powder as fine as dust. Then I threw it into the stream that came down from the mountain.
