Following are a number of back-translations as well as a sample translation for translators of 1 Chronicles 23:28:

• Kupsabiny: “The Levites were helping the priests when they were working in the Home of God. The Levites were guarding the courtyard of the Home of God and the rooms where the things that had been made from gold and silver were kept with other things of the House of God.. They made clean all the sacred (set apart) things. So, they did all the work which was according to the Home of God.” (Source: Kupsabiny Back Translation)
• Newari: “The work of the Levites was to help the descendants of Aaron with the conduct of worship in the temple of the LORD. To take care of the courtyard and rooms, to do the purification of sacred items, [and] to do other tasks for worship in the temple of God.” (Source: Newari Back Translation)
• Hiligaynon: “The obligation of the Levites was to help the priests who were the descendants of Aaron to serve in the temple of the LORD. They were the (ones who) would-take-care of the yards of the temple and the side rooms, and they were also the (ones who) would-help in the ceremonies of cleansing and some other works in the temple of God.” (Source: Hiligaynon Back Translation)
• English: “The work of those descendants of Levi was to assist the descendants of Aaron in their work in the temple of Yahweh: To be in charge of the temple courtyards and the side rooms, the ceremonies for purifying all the sacred things, and to do other work at the temple.” (Source: Translation for Translators)
