Following are a number of back-translations as well as a sample translation for translators of Psalm 127:1:

• Chichewa Contempary Chichewa translation, 2002/2016:
  “If Jehovah does not build the house,
  the builders of that house work in vain.
  If Jehovah does not guard a city,
  the guards would have guarded in vain.” (Source: Mawu a Mulungu mu Chichewa Chalero Back Translation)
• Newari:
  “If the Lord does not build the house,
  the work of those who build goes in vain.
  If the Lord does not protect the city,
  The watchman guards in vain.” (Source: Newari Back Translation)
• Hiligaynon:
  “If there-is-no help from the LORD,
  there/has-no value (in) the building a house or the watching-over a city.” (Source: Hiligaynon Back Translation)
• Laarim:
  “If the LORD does not build the house,
  the builders build for nothing.
  If the LORD does not protect the city,
  the guard will watch for nothing.” (Source: Laarim Back Translation)
• Nyakyusa-Ngonde (back-translation into Swahili):
  “BWANA iwapo hajajenga nyumba,
  ambao wanajenga wanafanya kazi ya bure.
  BWANA iwapo haulindi mji,
  walinzi wanajichosha bure.” (Source: Nyakyusa Back Translation)
• English:
  “If people are building a house without knowing whether it is Yahweh’s will to build it, they are building it in vain.
  Similarly, if Yahweh does not protect a city, it is useless for guards/sentries to stay awake to tell people if their enemies come to attack it.” (Source: Translation for Translators)
