'Banners' in the Bible

We will triumph in thy salvation, And in the name of our God we will set up our banners: Jehovah fulfil all thy petitions.

Thou art fair, O my love, as Tirzah, Comely as Jerusalem, Terrible as an army with banners.

Who is she that looketh forth as the morning, Fair as the moon, Clear as the sun, Terrible as an army with banners?
