Following are a number of back-translations as well as a sample translation for translators of Isaiah 49:15:

• Kupsabiny: “But God is saying,
  ‘Can a woman forget her child that she nursed?
  Can a woman really not have mercy on her child that she bore.
  Even if a woman forgets her child,
  I shall never forget you.” (Source: Kupsabiny Back Translation)
• Newari: “What! Will any mother forget her nursing child?
  What! Will she not have compassion on the child to which she has given birth?
  But even if a mother might forget
  I will never forget you. ” (Source: Newari Back Translation)
• Hiligaynon: “But the LORD replied, ‘Can a mother forget her child? Does she has no concern to what she had-given-birth? Even if she forgets, I will- never -forget you (plur.)!” (Source: Hiligaynon Back Translation)
• English: “But Yahweh replies,
  ‘That is not true! Can a woman forget the infant that she is nursing?/A woman certainly cannot forget the infant that she is nursing!
  Can she stop being kind to the child to whom she has given birth?/She certainly cannot stop being kind to the child to whom she has given birth!
  But even if a woman would do that,
  I will not forget you!” (Source: Translation for Translators)
