'Standard' in the Bible

“Lift up a standard toward Zion!Seek refuge, do not stand still,For I am bringing evil from the north,And great destruction.

How long must I see the standardAnd hear the sound of the trumpet?

“Declare and proclaim among the nations.Proclaim it and lift up a standard.Do not conceal it but say,‘Babylon has been captured,Bel has been put to shame, Marduk has been shattered;Her images have been put to shame, her idols have been shattered.’
