The Land of Cush
Isaiah 18:1-2
Woe to the land of whirring wings
along the rivers of Cush,
2 which sends envoys by sea
in papyrus boats over the water.
Go, swift messengers,
to a people tall and smooth-skinned,
to a people feared far and wide,
an aggressive nation of strange speech,
whose land is divided by rivers.
2 Chronicles 14:9
9 Zerah the Cushite marched out against them with an army of thousands upon thousands and three hundred chariots, and came as far as Mareshah.
