Following are a number of back-translations as well as a sample translation for translators of Nehemiah 13:22:

• Kupsabiny: “Then I told the Levites to purify themselves and guard the gates in order to safeguard the Sabbath.
  Be remembering these good things oh, my God! Be merciful to me in accordance with your love.” (Source: Kupsabiny Back Translation)
• Hiligaynon: “Then I commanded the Levites to-have- themselves -cleansed and guard the entrance/gates so-that the people will-consider a unique day the Day For-Resting.
  Then I prayed, ‘O my God, also remember this that I did, and have-mercy on me according to your (sing.) great love.’” (Source: Hiligaynon Back Translation)
• English: “I also commanded the descendants of Levi to perform the ritual to purify themselves and to guard the city gates, to make sure that the Sabbath was kept holy by not allowing merchants to enter it on Sabbath days.
  My God, do not forget this also that I have done for you! And because of your faithfully loving me, allow me to continue to live many more years!” (Source: Translation for Translators)
