Isaiah 5:26

26 He will raise a signal for a nation far away, and whistle for a people at the ends of the earth; Here they come, swiftly, speedily!

Isaiah 5:26 In-Context

24 Therefore, as the tongue of fire devours the stubble, and as dry grass sinks down in the flame, so their root will become rotten, and their blossom go up like dust; for they have rejected the instruction of the Lord of hosts, and have despised the word of the Holy One of Israel.
25 Therefore the anger of the Lord was kindled against his people, and he stretched out his hand against them and struck them; the mountains quaked, and their corpses were like refuse in the streets. For all this his anger has not turned away, and his hand is stretched out still.
26 He will raise a signal for a nation far away, and whistle for a people at the ends of the earth; Here they come, swiftly, speedily!
27 None of them is weary, none stumbles, none slumbers or sleeps, not a loincloth is loose, not a sandal-thong broken;
28 their arrows are sharp, all their bows bent, their horses' hoofs seem like flint, and their wheels like the whirlwind.
