'Rubbish' in the Bible

He spoke before his brothers and the army of Samaria, and said, "What are these feeble Jews doing? Will they fortify themselves? Will they sacrifice? Will they finish in a day? Will they revive the stones out of the heaps of rubbish, since they are burned?"

Judah said, "The strength of the bearers of burdens is fading, and there is much rubbish; so that we are not able to build the wall."
