'Grinding' in the Bible

And I took your sin, the calf which ye had made, and burnt it with fire, and stamped it, grinding it very small, until it was as fine as dust: and I cast the dust thereof into the brook that descended out of the mount.

and the doors shall be shut in the street; when the sound of the grinding is low, and one shall rise up at the voice of a bird, and all the daughters of music shall be brought low;

two women'shall be grinding at the mill; one is taken, and one is left.

There shall be two women grinding together; the one shall be taken, and the other shall be left.
