'Rubbish' in the Bible

And he spake before his brethren and the army of Samaria, and said, What do these feeble Jews? will they fortify themselves? will they sacrifice? will they make an end in a day? will they revive the stones out of the heaps of the rubbish which are burned?

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