Isaiah 5:26-28

¶He will lift up a flag to [call] the distant nations [to bring His judgment on Judah], And will whistle for them from the ends of the earth; And indeed, they will come with great speed swiftly. No one among them is weary or stumbles, No one slumbers or sleeps; Nor is the belt at their waist undone [as if unprepared for action], Nor is the strap of their sandal broken. Their arrows are sharp and all their bows are strung and bent; Their horses’ hoofs seem like flint and their chariot wheels like a whirlwind.
