Following are a number of back-translations as well as a sample translation for translators of Isaiah 56:7:

• Kupsabiny: “He is saying,
  ‘I shall bring you to come to my mountain that is holy
  and I shall make for you to be happy in my Home of prayer.
  I shall accept your offerings and the things that
  you give there on the altar.
  It is like that because my Home is (one) of prayer
  and it also belongs to all communities.’” (Source: Kupsabiny Back Translation)
• Newari: “these I will bring to my holy mountain.
  I will allow [them] to rejoice in my house of prayer.
  They will accept the burnt offerings and sacrifices they offer on my altar.
  For my house will be a house of prayer for all nations."” (Source: Newari Back Translation)
