Charles Ellicott Commentary Amos 3:10

"For they know not to do right, saith Jehovah, who store up violence and robbery in their palaces." — Amos 3:10 (ASV)

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