Obadiah compares the coming loss to thieves or grape gatherers, but says Edom’s plundering will be unusually thorough (Obadiah 1:5–6). He adds that Edom’s allies will drive it to the border and those who eat its bread will set a trap for it (Obadiah 1:7).
In Obadiah 1:5–7 the prophet portrays Edom’s coming ruin as unusually thorough. Ordinary thieves take only what they want, and harvesters leave something behind, but Edom will be stripped far beyond that. The lament then turns to betrayal: Edom’s allies and trusted table-companions will escort them to the edge, trick them, and overpower them. These verses sit within Obadiah’s opening announcement of Edom’s downfall (Obadiah 1:1–9), which moves from Edom’s proud security to the certainty of collapse. Verses 5–7 sharpen the picture by using everyday comparisons (thefts and grape harvest) to show that this disaster will not be partial or restrained.
Obadiah 1:5–7 presents Edom’s downfall as unusually complete. The prophet uses everyday comparisons: thieves typically stop once they have enough, and grape harvesters usually leave some leftover clusters. By contrast, Edom will be stripped beyond what people would expect from ordinary raiding or normal wartime loss (explicit in the text’s contrasts).
A careful answer keeps the immediate passage, the book's argument, and the whole-Bible storyline together, so the question is answered in context instead of as a detached idea.
Start with Obadiah 1:5-6, then read the surrounding section so the answer stays connected to the passage's flow.
5If thieves came to you, if robbers by night -- oh, what disaster awaits you -- wouldn`t they only steal until they had enough? If grape pickers came to you, wouldn`t they leave some gleaning grapes?
6How Esau will be ransacked! How his hidden treasures are sought out!
