Following are a number of back-translations as well as a sample translation for translators of Isaiah 60:21:

• Kupsabiny: “All your people shall be righteous
  and the land shall be yours forever.
  Those people are seeds that I planted with my hands
  so that I then could be raised up/exalted.” (Source: Kupsabiny Back Translation)
• Newari: “After that all your people will be righteous,
  They will always possess the land.
  [They are] like a small plant that I have planted to show my glory,
  and they are the work of my hand.” (Source: Newari Back Translation)
• Hiligaynon: “All your (sing.) people will be righteous, and they will-possess the land of Israel forever/[lit. until whenever]. I created them; they are like plant which I planted for my honor.” (Source: Hiligaynon Back Translation)
