Following are a number of back-translations as well as a sample translation for translators of Nehemiah 13:21:

• Kupsabiny: “Then I became tough while saying to them, ‘Why do you stay outside the wall like that? I will send you away if you again act this way.’ That became the last time those people came on the Sabbath day.” (Source: Kupsabiny Back Translation)
• Hiligaynon: “But I warned them. I said, ‘Why do- you (plur.) -sleep here by the stone-wall of the city? If you (plur.) do this again I (sing.) will- surely -lay-hands-on/take-action-on/[lit. can surely taste from me] you (plur.).’ Therefore since that they no-longer return on the Day For-Resting.” (Source: Hiligaynon Back Translation)
• English: “I warned them, ‘It is useless for you to stay here outside the walls on Friday night! If you do this again, I will tell my men to arrest you!’ So after that, they did not come on Sabbath days.” (Source: Translation for Translators)
