1Ah, the land of the rustling of wings, which is beyond the rivers of Ethiopia; 2that sends ambassadors by the sea, even in vessels of papyrus on the waters, [saying], Go, you swift messengers, to a nation tall and smooth, to a people awesome from their beginning onward, a nation that measures out and treads down, whose land the rivers divide!
