Isaiah 18:1-3

1Ha! land shadowing with wings, which art beyond the rivers of Cush,

2that sendest ambassadors over the sea, and in vessels of papyrus upon the waters, [saying,] Go, swift messengers, to a nation scattered and ravaged, to a people terrible from their existence and thenceforth; to a nation of continued waiting and of treading down, whose land the rivers have spoiled!

3All ye inhabitants of the world, and dwellers on the earth, when a banner is lifted up on the mountains, see ye, and when a trumpet is blown, hear ye!
