  you are honored and I love you.
  So, I give out other nations for you (plur.)
  and I will exchange other countries for your life.” (Source: Kupsabiny Back Translation)
• Newari: “Because you are very precious in my eyes and are honored,
  because I love you
  I will give people in place of you
  and nations instead of your life.” (Source: Newari Back Translation)
• Hiligaynon: “I will-hand-over the other people-groups instead of you (sing.), because you (sing.) are precious/valuable/[lit. of-great-price] and honorable in my sight, and because I love you (sing.).” (Source: Hiligaynon Back Translation)
