As Moab is related in some way to the Israel, despite the literaty closures, this part with the others seem to form a larger pattern. The crime of Moab probably is more about sacrilege, with bones figure mentioned also in 6:9–10; verse 2b echoing 1:14b; and the trumpet reappears in 3:6, in a similar context.
Verses 1–3
Verse 1 notes
"He burned the bones of the King of Edom into lime": This profanation of the corpse by the Moab people is not mentioned in any historical documents. Some historical commentators, such as Jacobus Tirinus and Cornelius a Lapide, think that the prophet wants to show that 'the sympathy of God extends beyond the covenant people, and that he punishes wrongs inflicted even on heathen nations'. The event probably happened in relation to the coalition of the king of Edom with Jehoram and Jehoshaphat against Mesha, the King of Moab, who made inscription on Mesha Stele at Dibon mentioned the war against Edom Jerome quotes a Jewish tradition stating that after this war the Moab people dug up and dishonored the bones of king of Edom in revenge for the assistance he had given to the Israelites. Edom was then a vassal of Judah, but regained its independence about ten years later.
Verse 4
"For three transgressions of Judah": There is no difference in the treatment of Jews and Gentiles (cf. Romans 2:12. "...as many as have signed in the law, shall be judged by the law", as Jerome notes "those other nations, Damascus and the rest, he upbraids not for having cast away the law of God, and despised His commandments, for they had not the written law, but that of nature only. So then of them he says, that "they corrupted all their compassions"... but Judah... had the worship of God and the temple and its rites, and had received the law and commandments... is rebuked and convicted by the Lord, for that it had "cast aside His law and not kept His commandments;" wherefore it should be punished as it deserved".
Verse 10
"Also I": Used by God to remind the people of the good things he did as a motive to obedience.
"Forty years through the wilderness": During those "forty years" the law was rehearsed and the people were daily supplied with the manna, the water from the rock, as well as the deliverance from the serpents and other dangers, so the journey through the wilderness was not just a punishment but also a blend of kindness.
"The land of the Amorite": refers to the whole land of Canaan as the Amorites were the principal nation of it in the past.
