filled - glutted. The image of a sacrifice is continued.
blood ... fat - the parts especially devoted to God in a sacrifice (2Sa 1:22).
lambs ... goats - sacrificial animals: the Idumeans, of all classes, doomed to slaughter, are meant (Zep 1:7).
Bozrah - called Bostra by the Romans, etc., assigned in Jer 48:24 to Moab, so that it seems to have been at one time in the dominion of Edom, and at another in that of Moab (Isa 63:1; Jer 49:13, Jer 49:20, Jer 49:22); it was strictly not in Edom, but the capital of Auranitis (the Houran). Edom seems to have extended its dominion so as to include it (compare Lam 4:21).
