Isaiah 6:10-12

10Make the heart of this people calloused; make their ears dull and close their eyes. Otherwise they might see with their eyes, hear with their ears, understand with their hearts, and turn and be healed.” 11Then I said, “For how long, Lord?” And he answered: “Until the cities lie ruined and without inhabitant, until the houses are left deserted and the fields ruined and ravaged, 12until the Lord has sent everyone far away and the land is utterly forsaken.
