Jeremiah 6:22-23

Thus says the Lord: Behold, a people is coming from the north country, and a great nation is arousing itself from the ends of the earth. They lay hold on bow and spear; they are cruel (ruthless and inhuman) and have no mercy. Their voice sounds like the roaring sea; they ride on horses, every one set in array as a man for battle against you, O Daughter of Zion!
