God in care of his people will destroy the Ethiopians.
Isaiah 18:1 Ah, the land of the rustling of wings, which is beyond the rivers of Ethiopia: Isaiah 18:2 that sendeth ambassadors by the sea, even in vessels of papyrus upon the waters, [saying], Go, ye swift messengers, to a nation tall and smooth, to a people terrible from their beginning onward; a nation that meteth out and treadeth down, whose land the rivers divide! Isaiah 18:3 All ye inhabitants of the world, and ye dwellers on the earth, when an ensign is lifted up on the mountains, see ye; and when the trumpet is blown, hear ye. Isaiah 18:4 For thus hath the LORD said unto me, I will be still, and I will behold in my dwelling place; like clear heat in sunshine, like a cloud of dew in the heat of harvest. Isaiah 18:5 For afore the harvest, when the blossom is over, and the flower becometh a ripening grape, he shall cut off the sprigs with pruning-hooks, and the spreading branches shall he take away [and] cut down. Isaiah 18:6 They shall be left together unto the ravenous birds of the mountains, and to the beasts of the earth: and the ravenous birds shall summer upon them, and all the beasts of the earth shall winter upon them.
An access thereby shall grow unto the Church.
Isaiah 18:7 In that time shall a present be brought unto the LORD of hosts of a people tall and smooth, and from a people terrible from their beginning onward; a nation that meteth out and treadeth down, whose land the rivers divide, to the place of the name of the LORD of hosts, the mount Zion.
