6. Israel--the ten tribes, the main subject of Amos' prophecies.
      sold the righteous--Israel's judges for a bribe are induced to condemn in judgment him who has a righteous cause; in violation of De 16:19.
      the poor for a pair of shoes--literally, "sandals" of wood, secured on the foot by leather straps; less valuable than shoes. Compare the same phrase, for "the most paltry bribe," Am 8:6; Eze 13:19; Joe 3:3. They were not driven by poverty to such a sin; beginning with suffering themselves to be tempted by a large bribe, they at last are so reckless of all shame as to prostitute justice for the merest trifle. Amos convicts them of injustice, incestuous unchastity, and oppression first, as these were so notorious that they could not deny them, before he proceeds to reprove their contempt of God, which they would have denied on the ground that they worshipped God in the form of the calves.
