Following are a number of back-translations as well as a sample translation for translators of Isaiah 57:5:

• Kupsabiny: “The desire of your bodies push/entice you
  and you practice illicit sex under every green tree.
  You offer your children to be killed in the valley
  and where there is an open ground.” (Source: Kupsabiny Back Translation)
• Newari: “Staying among the sacred oak trees
  and staying like lust under all the spreading trees.
  You sacrifice your sons and daughters in the gorge
  and on the cliff.” (Source: Newari Back Translation)
• Hiligaynon: “You (plur.) worship your (plur.) little-gods/false-gods by having-sex under every leafy tree. You (plur.) even sacrifice your (plur.) children in the places-where- water -flows under the cliffs.” (Source: Hiligaynon Back Translation)
