Esias 5:28

28 Whose arrows are sharp, and their bows bent; their horses' hoofs are counted as solid rock: their chariot-wheels are as a storm.

Esias 5:28 In-Context

26 Therefore shall he lift up a signal to the nations that are afar, and shall hiss for them from the end of the earth; and, behold, they are coming very quickly.
27 They shall not hunger nor be weary, neither shall they slumber nor sleep; neither shall they loose their girdles from their loins, neither shall their shoe-latchets be broken.
28 Whose arrows are sharp, and their bows bent; their horses' hoofs are counted as solid rock: their chariot-wheels are as a storm.
29 They rage as lions, and draw nigh as a lion's whelps: and he shall seize, and roar as a wild beast, and he shall cast forth, and there shall be none to deliver them.
30 And he shall roar on account of them in that day, as the sound of the swelling sea; and they shall look to the land, and, behold, thick darkness in their perplexity.
