Isaiah 34:7 in the King James Version
And the unicorns shall come down with them, and the bullocks with the bulls; and their land shall be soaked with blood, and their dust made fat with fatness.
Context
6 The LORD’s sword is filled with blood. It is covered with fat, with the blood of lambs and goats, with the fat of the kidneys of rams; for the LORD has a sacrifice in Bozrah, and a great slaughter in the land of Edom.
7 The wild oxen will come down with them, and the young bulls with the mighty bulls; and their land will be drunken with blood, and their dust made greasy with fat.
8 For the LORD has a day of vengeance, a year of recompense for the cause of Zion.
