Following are a number of back-translations as well as a sample translation for translators of 2 Chronicles 36:21:

• Kupsabiny: “That fulfilled the words that God had said through Jeremiah that their fields were to rest for seventy years without being tilled.” (Source: Kupsabiny Back Translation)
• Newari: “To fulfill the word of the LORD which came from the mouth of Jeremiah, until 70 years have passed, as long as it was standing desolate, the land was honoring its years of rest.” (Source: Newari Back Translation)
• Hiligaynon: “So what the LORD had-said through prophetJeremias that the land will-become desolate and it will-rest within the (period) of 70 years was-fulfilled.” (Source: Hiligaynon Back Translation)
• English: “Moses had said that every seventh year the people must not plant their fields; they must allow the soil to rest. But the people had not done that. So after the army of Babylonia destroyed Judah, the soil was allowed to rest. That continued for 70 years, fulfilling what Yahweh told Jeremiah and what Jeremiah had predicted/prophesied would happen.” (Source: Translation for Translators)
