In Siege of Jerusalem (597 BC), Nebuchadnezzar II sacked Jerusalem, carted away the King of Judah, and installed a puppet ruler. The Edomites helped the Babylonians loot the city. Obadiah, writing this prophecy around 590 BCE, suggests the Edomites should have remembered that blood was thicker than water. "On the day you stood aloof while strangers carried off his wealth and foreigners entered his gates and cast lots for Jerusalem, you were like one of them... You should not march through the gates of my people in the day of their disaster, nor gloat over them in their calamity in the day of their disaster, nor seize their wealth in the day of their disaster." ( NIV)
