Charles Ellicott Commentary Isaiah 30:14

"And he shall break it as a potter`s vessel is broken, breaking it in pieces without sparing; so that there shall not be found among the pieces thereof a sherd wherewith to take fire from the hearth, or to dip up water out of the cistern." — Isaiah 30:14 (ASV)
