The Lord hath a sacrifice in Bozrah... — Two cities of this name appear in history; one in the Haurân, more or less conspicuous in ecclesiastical history, and the other, of which Isaiah now speaks, in Edom. It was a strongly fortified city, and is named again and again. (Comp. Isaiah 63:1; Amos 1:12; Jeremiah 49:13; Jeremiah 49:22.) The image both of the sword and the sacrifice appears in Jeremiah 46:10.

6 The sword of the LORD is filled with blood, it is made fat with fatness, and with the blood of lambs and goats, with the fat of the kidneys of rams: for the LORD hath a sacrifice in Bozrah, and a great slaughter in the land of Idumea.
