Following are a number of back-translations as well as a sample translation for translators of Esther 3:7:

• Kupsabiny: “In the first month of the twelfth year while Ahasuerus was ruling, then Haman said that lots should be cast to know the day and the month when the Jews were to be killed. Those lots were called ‘Purim.’ Those lots fell on the thirteenth day of the twelfth month.” (Source: Kupsabiny Back Translation)
• Newari: “In the 12th year of [the reign of] king Ahasuerus in the first month, the month of Nisan, lots were cast in Haman’s presence to decide the [best] day and month [to take action]. The lots were called "Pur." The lot fell on a day in the 12th month, the month of Adar.” (Source: Newari Back Translation)
• Hiligaynon: “In the first month, which was the month of Nisan, on the twelfth month of Ahasuerus’s reign, Haman commanded to cast-lots in-order to know what is the right day and month to fulfill/execute his plan. (The thing they used to cast-lots is called ‘pur.’) The one-that-was-selected was the 13th day of the 12th, which was the month of Adar.” (Source: Hiligaynon Back Translation)
• Eastern Bru: “In the first month (the month Nasan) in the twelfth year of Xerxes’s kingdom, Haman had someone get the things they use to cast lots. Those things they call ‘Purim’.) He chose a day and month that was good to kill all the Jews. The lot fell on the thirteenth day of the twelfth month (the month Adar).” (Source: Bru Back Translation)
• English: “So, during the twelfth year that Xerxes was ruling, during the month of April, Haman told his advisors to cast lots/throw small marked stones to determine the best month and the best day to kill the Jews. Haman’s advisors did that, and the day that was selected was March 7th during the following/next year.” (Source: Translation for Translators)
