Who is "us", and who is "we"?

Isaiah 41:21 Produce your cause, saith the LORD; bring forth your strong reasons, saith the King of Jacob.

  22 Let them bring them forth, and shew us what shall happen: let them shew the former things, what they be, that we may consider them, and know the latter end of them; or declare us things for to come.

  23 Shew the things that are to come hereafter, that we may know that ye are gods: yea, do good, or do evil, that we may be dismayed, and behold it together.

  26 Who hath declared from the beginning, that we may know? and beforetime, that we may say, He is righteous? yea, there is none that sheweth, yea, there is none that declareth, yea, there is none that heareth your words.
