Isaiah 18:3-7

3All 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.

4For thus hath Jehovah 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. 5For before the harvest, when the blossom is over, and the flower becometh a ripening grape, he will cut off the sprigs with pruning-hooks, and the spreading branches will he take away and cut down. 6They 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. 7In that time shall a present be brought unto Jehovah of hosts from a people tall and smooth, even 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 Jehovah of hosts, the mount Zion.
