Following are a number of back-translations as well as a sample translation for translators of 2 Chronicles 30:6:

• Kupsabiny: “Then, the king and the leaders wrote letters and gave to messengers to bring to every area of Israel and Judah. Those news said, ‘Stomach of Israel, return (plur.) to the God of Abraham, Isaac and Jacob. When/If you do that, God will also receive/welcome you who are the remainder who have escaped the hands of the king of Assyria.” (Source: Kupsabiny Back Translation)
• Newari: “So people taking letters from the king and his courtiers, who went to give the message in accordance with the king’s command, walked all over Israel and Judah speaking like this —
  "O people of Israel! Even though the Assyrians conquered the land, you have been delivered from their hand. Return to the LORD, the God of Abraham, Isaac, and Israel and he will return to you!” (Source: Newari Back Translation)
• Hiligaynon: “At the command of the king, the messengers went throughout Israel and Juda with letters from the king and his officials. This is (what) the letter is-saying:
  ‘People of Israel, now that you (plur.) were able-to-escape from the hand of the kings of Asiria, (it is) time now that you (plur.) will-return to the LORD, the God of your ancestors who were Abraham, Isaac, and Jacob, so-that he will-return to you too.” (Source: Hiligaynon Back Translation)
• English: “Obeying what the king commanded, messengers went throughout Judah and Israel, taking messages that had been written by the king and his officials. This is what they wrote:
  ‘You Israeli people, you who survived after being slaves of the kings of Assyria, return to Yahweh, the God whom our great ancestors Abraham, Isaac, and Jacob worshiped/belonged to, in order that he may return to you. Your fathers and brothers did not faithfully obey Yahweh, the God whom our ancestors worshiped.” (Source: Translation for Translators)
