2:1-8 The evil passions of the heart break out in various forms; but the Lord looks to our motives, as well as our conduct. Those that deal cruelly, shall be cruelly dealt with. Other nations were reckoned with for injuries done to men; Judah is reckoned with for dishonour done to God. Judah despised the law of the Lord; and he justly gave them up to strong delusion; nor was it any excuse for their sin, that they were the lies, the idols, after which their fathers walked. The worst abominations and most grievous oppressions have been committed by some of the professed worshippers of the Lord. Such conduct leads many to unbelief and vile idolatry.
Am 2:1-16. Charges against Moab, Judah, and Lastly Israel, the Chief Subject of Amos' Prophecies.
1. burned … bones of … king of Edom into lime—When Jehoram of Israel, Jehoshaphat of Judah, and the king of Edom, combined against Mesha king of Moab, the latter failing in battle to break through to the king of Edom, took the oldest son of the latter and offered him as a burnt offering on the wall (2Ki 3:27) [Michaelis]. Thus, "king of Edom" is taken as the heir to the throne of Edom. But "his son" is rather the king of Moab's own son, whom the father offered to Molech [Josephus, Antiquities, 9.3]. Thus the reference here in Amos is not to that fact, but to the revenge which probably the king of Moab took on the king of Edom, when the forces of Israel and Judah had retired after their successful campaign against Moab, leaving Edom without allies. The Hebrew tradition is that Moab in revenge tore from their grave and burned the bones of the king of Edom, the ally of Jehoram and Jehoshaphat, who was already buried. Probably the "burning of the bones" means, "he burned the king of Edom alive, reducing his very bones to lime" [Maurer].
