Jeremiah 50:9-10

Yahweh promised to become active again for His people and to bring many great nations from the north against Babylon. After a battle, Babylon would fall. The enemy would be skillful in archery and would take many captives. The enemy would take so much plunder that he would be satisfied. The references to "many nations" and "the north" point to a future fulfillment, in addition to a partial past fulfillment.
