'Empty' in the Bible

They will know that I am the Lord; my threats to bring this catastrophe on them were not empty.'

"'Therefore this is what the sovereign Lord says: Woe to the city of bloodshed, the pot whose rot is in it, whose rot has not been removed from it! Empty it piece by piece. No lot has fallen on it.

Set the empty pot on the coals, until it becomes hot and its copper glows, until its uncleanness melts within it and its rot is consumed.
