Following are a number of back-translations as well as a sample translation for translators of Isaiah 51:18:

• Kupsabiny: “There was not even one of the children you bore
  who would take you by the hand and lead you,
  and there was not a single child whom you took care of
  who took you by the hand and showed you the way.” (Source: Kupsabiny Back Translation)
• Newari: “Among all the sons to whom she gave birth
  there are none to guide her
  Among the sons that she brought up
  there were none who would hold her hand and bring [her] along.” (Source: Newari Back Translation)
• Hiligaynon: “No one of your (sing.) people will-guide you (sing.); no one among them will-help you (sing.).” (Source: Hiligaynon Back Translation)
