Jeremiah 50:42 in the World English Bible
They take up bow and spear. They are cruel, and have no mercy. Their voice roars like the sea. They ride on horses, everyone set in array, as a man to the battle, against you, daughter of Babylon.
Context
41 Behold, a people shall come from the north, and a great nation, and many kings shall be raised up from the coasts of the earth.
42 They shall hold the bow and the lance: they are cruel, and will not shew mercy: their voice shall roar like the sea, and they shall ride upon horses, every one put in array, like a man to the battle, against thee, O daughter of Babylon.
43 The king of Babylon hath heard the report of them, and his hands waxed feeble: anguish took hold of him, and pangs as of a woman in travail.
