Isaiah 34:6

Is filled with blood; shall drink its fill of blood. The metaphor is here taken from a great glutton or drunkard, who is almost insatiable with meat and drink. With the blood of lambs and goats, with the fat of the kidneys of rams: by, lambs, and goats, and rams, he means people of all ranks and conditions, high and low, rich and poor. A sacrifice; so he calleth this bloody work, because it was done by God's command, and for his honour; and therefore was a service acceptable to him. Bozrah; a chief city of Edom, Isaiah 63:1 Jeremiah 49:13, and a type of those cities which should be most opposite and mischievous to God's people.
