'People of the Land' in the Bible

Say to all the people of the land and to the priests, When you went without food and gave yourselves to grief in the fifth and the seventh months for these seventy years, did you ever do it because of me?

For I will have no more pity for the people of the land, says the Lord; but I will give up everyone into his neighbour's hand and into the hand of his king: and they will make the land waste, and I will not keep them safe from their hands.
