Parallel
Isaiah 18:2
Brenton's English Septuagint · Berean Standard Bible
He sends messengers by the sea, and paper letters on the water: for swift messengers shall go to a lofty nation, and to a strange and harsh people. Who is beyond it? a nation not looked for, and trodden down.
which sends couriers by sea, in papyrus vessels on the waters. Go, swift messengers, to a people tall and smooth-skinned, to a people widely feared, to a powerful nation of strange speech, whose land is divided by rivers.
