Following are a number of back-translations as well as a sample translation for translators of Joshua 15:8:

• Kupsabiny: “After that, it followed the valley of Hinnom south of the city of the Jebusites (which later became Jerusalem). It went up to a mountain which overlooks the valley of Hinnom to the west which is also at the end of the valley of the Rephaites at the north end.” (Source: Kupsabiny Back Translation)
• Newari: “From there that boundary goes by way of the gorge of Ben-Hinnom and along the southern slopes of the city of the Jebusites which is Jerusalem. Then that boundary goes to the top of the hill which is to the west of the Hinnom gorge at the northern end of the Valley of Rephaim.” (Source: Newari Back Translation)
• Hiligaynon: “From there this goes-towards the Valley/Plain of Ben Hinom up-to the southern slope of the city of the Jebusnon. (This city is Jerusalem.) Then this goes-up to the peak/top of the mountain, to the west of the Valley of Ben Hinom, to the outlying-edge of the northern Valley of the Refaim.” (Source: Hiligaynon Back Translation)
• English: “From there it extended through Ben-Hinnom Valley, south of the city where the Jebus people-group lived. (That city is now named Jerusalem.) From there the border extended to the top of the hill on the west side of Hinnom Valley, at the northern end of the valley where the Repha giants lived.” (Source: Translation for Translators)
