'Banner' in the Bible

How long must I see [the] banner, [and] hear [the] sound of a horn?

"Declare among the nations and proclaim, and lift up a banner. Proclaim, you must not conceal [it]. Say, 'Babylon is captured, Bel is ashamed, Merodach is filled with terror, her idols are ashamed, her idols are filled with terror.

Against the walls of Babylon raise a banner; {post a strong watch}, post watchmen, prepare the ambushes, for Yahweh has both planned as well as performed what he has spoken concerning the inhabitants of Babylon.

Raise a banner in the land; blow a horn among the nations; prepare for holy war against her; summon [the] nations against her, the kingdoms of Ararat, Minni, and Ashkenaz; summon against her an official; bring up horses like bristling creeping locusts.
