Following are a number of back-translations as well as a sample translation for translators of 1 Chronicles 6:49:

• Kupsabiny: “It was only Aaron and the people from his house/family who was given to make sacrifices. They made sacrifices at the altar where sacrifices were burnt completely and where things that smell sweet were burned. They were the ones who were in charge of all the work in the Inner Room of the House of God. They made sacrifices which reconciled people to return to God following how Moses the servant of God had said.” (Source: Kupsabiny Back Translation)
• Newari: “However, only Aaron and his descendants had permission to offer burnt offerings on the altar of burnt offerings and to offer incense in the clay pot for burning embers. It was their responsibility to offer burnt offerings in seeking pardon for sin from God and for all the work of worship which was done in the most holy place. They did all that work according to the commands given by Moses, who served God.” (Source: Newari Back Translation)
• Hiligaynon: “But Aaron and his descendants were only/just the (ones) made priests. They (were) the (ones-who) were-offering on the altar the being-burnt offering(s) and on the altar which (is) the place-of-burning of incense. And they were- also the -ones-who-did the other works/duties that were-connected with the Most Holy Place. They offered so-that the Israelinhon would-be-saved/redeemed from their sins.” (Source: Hiligaynon Back Translation)
• English: “Aaron and his descendants were the ones who placed on the altar the sacrifices that were to be burned completely, and they burned incense on another altar. Those sacrifices were in order that Yahweh would no longer be angry with the people of Israel for having sinned. Those men also did other work in the Very Holy Place in the sacred tent, obeying the instructions that Moses, who served God well, had given to them.” (Source: Translation for Translators)
