'Joints' in the Bible

The stands were constructed with frames between the joints.

On these frames and joints were ornamental lions, bulls, and cherubs. Under the lions and bulls were decorative wreaths.

And a certain man drew a bow at a venture, and smote the king of Israel between the joints of the harness: wherefore he said unto the driver of his chariot, Turn thine hand, and carry me out of the host; for I am wounded.
