Following are a number of back-translations as well as a sample translation for translators of Ezekiel 40:21:

• Kupsabiny: “It also had three rooms on both sides. The three rooms on this side and the other side of the gate were equal to those of the gate that was at the side of East and also the walls that separated those rooms were equal/the same and also the veranda/portico. (They/It) had a length of eighty-seven and a half feet and a width of forty-four feet.” (Source: Kupsabiny Back Translation)
• Hiligaynon: “Each side of the way there were also three rooms where the guards watched. The size of these rooms and of the stone-walls in the center of it, and including its balcony, were also the same in the east way. The length of the way in the north was 85 feet and its width was 42 and a half feet.” (Source: Hiligaynon Back Translation)
• English: “There were three alcoves on each side of the entryway hall. The measurements of the alcoves, the dividing walls between the alcoves, and the entry room were the same as as those in the first entryway. The length from theouter opening of the entryway to the far end of the entry room was 87-1/2 feet/26.5 meters. The entryway was 43-3/4 feet/13.3 meters wide.” (Source: Translation for Translators)
