'Rebuild' in the Bible

So I prayed to the God of heaven and I replied to the king, "If it seems good to you, and if your servant has found favor with you, would you send me to Judah, to the city where my ancestral sepulchers are located, so I can rebuild it?"

Later I told them, "You all are watching the predicament we're in, how Jerusalem lies desolate, with its gates burned by fire. Let's rebuild the Jerusalem wall so we're no longer a disgrace."

He addressed his allies and the Samaritan officials, saying "What are these pathetic Jews doing? Are they intending to rebuild it by themselves? Do they intend to offer sacrifices? Will they finish in a single day? Can they make stones from this burned out rubble?"
