Following are a number of back-translations as well as a sample translation for translators of Jeremiah 33:21:

• Kupsabiny: “And in a way like that, I made my covenant with my servant David, for/so that a person from his descendants would rule. And again, there will always be priests from the house of Levi who will serve me.” (Source: Kupsabiny Back Translation)
• Hiligaynon: “likewise my covenant with David my servant will- not -be-changed that he (will) always have a descendant who will-reign. And also with the priests who are the descendants of Levi, they will-serve me as usual.” (Source: Hiligaynon Back Translation)
• English: “Similarly, you cannot annul the promise/agreement that I made with King David, who served me well, that there will always be descendants of his who will rule Judah. The same is true for my agreement with the descendants of Levi who are priests who do work for me.” (Source: Translation for Translators)
