Jeremiah 50:44
44
Behold, [the enemy] shall come up like a lion from the pride of the Jordan against the strong habitation: for I will suddenly make them run away from it; and whoever is chosen, him will I appoint over it: for who is like me? and who will appoint me a time? and who is the shepherd who can stand before me?
