Following are a number of back-translations as well as a sample translation for translators of 1 Kings 12:33:

• Kupsabiny: “Jeroboam set aside the fifteenth day of the eighth month to become a feast day like the festive day in Judah. He also called the priests whom he had chosen to go to Bethel. But on the feast day which he had arranged, he went to Bethel. Then, he went up to the altar and burnt sweet-smelling things. Then, sacrifices were burnt to that idol which was worshipped.” (Source: Kupsabiny Back Translation)
• Newari: “So on the 15th day of the 8th month, the day he himself had chosen, he went to Bethel to offer sacrifices on the altar he had built there. He started a festival for the Israelites, and he went to offer sacrifices on the altar.” (Source: Newari Back Translation)
