'Rubbish' in the Bible

He spoke before his brothers and the army of Samaria, “What are these feeble Jews doing? Can they restore it for themselves? Can they offer sacrifices? Can they finish in a day? Can they revive the stones from the heaps of dust and rubbish, even the ones that have been burned?”

Then [the leaders of] Judah said,“The strength of the burden bearers is failing,And there is much rubble;We ourselves are unableTo rebuild the wall.”
