'Common People' in the Bible

"'If anyone of the common people sins unwittingly, in doing any of the things which the LORD has commanded not to be done, and is guilty;

He brought out the Asherah from the house of the LORD, outside of Jerusalem, to the brook Kidron, and burned it at the brook Kidron, and beat it to dust, and cast its dust on the graves of the common people.

and they fetched forth Uriah out of Egypt, and brought him to Jehoiakim the king, who killed him with the sword, and cast his dead body into the graves of the common people."

David himself calls him Lord, so how can he be his son?" The common people heard him gladly.
