Following are a number of back-translations as well as a sample translation for translators of Joshua 8:31:

• Kupsabiny: “as it had been written in the book of Moses, ‘Build for me an altar of stones which have not been planed/smoothened and have not been touched by any piece of iron.’ The people made sacrifices for God there which were burned completely and those of fellowship.” (Source: Kupsabiny Back Translation)
• Newari: “in accordance with the command that Moses, the servant of the LORD gave the Israelites. He built it of stones which was not touched by iron tools, on it they offered burnt offerings and fellowship offerings for the LORD.” (Source: Newari Back Translation)
• Hiligaynon: “He had- this -built according-to the command of Moises, the servant of the LORD, to the Israelinhon. This command was-written in the Book of the Law of Moises, and this is what (it) says there: ‘[You (sing.)] build a stone altar which has-not been-cut/chipped or shaped with an iron tool.’ On top of the altar they offered to the LORD burnt offerings and offerings for a good relationship.” (Source: Hiligaynon Back Translation)
• English: “They built it just like Moses, the man who served God well, had written previously in the laws that God had given to him. They made it from stones that had not been cut using iron tools. The Israelis then offered sacrifices to Yahweh that were burned completely on the altar. They also offered sacrifices to restore fellowship with Yahweh.” (Source: Translation for Translators)
