'Rubbish' in the Bible

and saith before his brethren and the force of Samaria, yea, he saith, 'What are the weak Jews doing? are they left to themselves? do they sacrifice? do they complete in a day? do they revive the stones out of the heaps of the rubbish? -- and they burnt!'

And Judah saith, 'The power of the burden-bearers hath become feeble, and the rubbish is abundant, and we are not able to build on the wall.'
