Jeremiah 50:40-42
English Standard Version
41 "Behold, a people comes from the north; a mighty nation and many kings are stirring from the farthest parts of the earth.
42They lay hold of bow and spear; they are cruel and have no mercy. The sound of them is like the roaring of the sea; they ride on horses, arrayed as a man for battle against you, O daughter of Babylon!
