Amos 3:10

Know not to do right. — Not merely have lost the perception of what is and what is not right, but are indifferent to such distinctions. They know not and care not; the awful state of utter moral impotence, wherein not only the intellectual consciousness, but the impulses to action, are languid or even paralysed — a dead conscience! Nothing is more condemnatory than this brief sentence. The light within them is darkness.
