'Doing' in the Bible

But when Sanballat the Horonite and Tobiah the Ammonite official and Geshem the Arab heard about it, they mocked us and regarded us with contempt and said, “What is this thing you are doing? Are you rebelling against the king?”

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?”

So I said, “What you are doing is not good. Should you not walk in the fear of our God to prevent the taunting by the [pagan] nations, our enemies?

So I sent messengers to them, saying, “I am doing a great work and cannot come down. Why should the work stop while I leave to come down to [meet with] you?”
