Rhetorical questions in Obadiah 5 (LEB):
“If thieves came to you, if plunderers of the night—How you have been destroyed!—would they not steal ⌊what they wanted⌋? If grape gatherers came to you, would they not leave gleanings?
On the Naked Bible Podcast episodes on Obadiah (starting around 27:00), Dr. Mike Heiser understands the answers to both questions to be "no": robbers would take everything, harvesters would leave nothing, and, in the same way, Edom will be completely destroyed.
But the authors of the NET Bible say the questions anticipate "yes": robbers and harvesters would have left something behind, even something insignificant, but, not in the same way, Edom will be completely destroyed.
sn Obadiah uses two illustrations to show the totality of Edom’s approaching destruction. Both robbers and harvesters would have left at least something behind. Such will not be the case, however, with the calamity that is about to befall Edom. A virtually identical saying appears in Jer 49:9-10.
tn Heb “Would they not have left some gleanings?” The rhetorical question makes an emphatic assertion, which for the sake of clarity is represented by the indicative form in the translation. The implied answer to these rhetorical questions is “yes.” The fact that something would have remained after the imagined acts of theft or harvest stands in stark contrast to the totality of Edom’s destruction as predicted by Obadiah. Edom will be so decimated as a result of God’s judgment that nothing at all will be left sn According to the Mosaic law, harvesters were required to leave some grain behind in the fields for the poor (Lev 19:9; 23:22; see also Ruth 2); there was a similar practice with grapes and olives (Lev 19:10; Deut 24:21). Regarding gleanings left behind from grapes, see Judg 8:2; Jer 6:9; 49:9; Mic 7:1.
I'm inclined to the NET authors' reading, considering the mention of "gleanings", but I'm uncertain. Which reading is more coherent with the text?
