obdurate

The sheep, however, cried not out to them, neither did they hear what they uttered to them; but were deaf, blind, and obdurate in the greatest degrees.

Woe to you, ye obdurate in heart, who commit crime, and feed on blood. Whence _is it that_ you feed on good things, drink, and are satiated? Is it not because our Lord, the Most High, has abundantly supplied every good thing upon earth? To you there shall not be peace.
