Following are a number of back-translations as well as a sample translation for translators of Isaiah 37:23:

• Kupsabiny: “Who is it that you have insulted and spoken badly about?
  Who did you shout at and sneer at?
  You did it to the Righteous one of Israel.” (Source: Kupsabiny Back Translation)
• Newari: “Who have you been insulting and abusing?
  and against whom did you speak out and act pretentiously?
  It was against the holy God of Israel, wasn’t it!” (Source: Newari Back Translation)
• Hiligaynon: “Whom have- you (sing.) -insulted and blasphemed? Whom have- you (sing.) -raised-up your (sing.) voice and boasted-upon? It is not I, the Holy God of Israel?” (Source: Hiligaynon Back Translation)
• English: “Whom do you think you have been despising and ridiculing?
  Whom do you think you were shouting at?
  Whom do you think you were looking at very proudly/arrogantly?
  It was I, the Holy One whom the Israelis worship!” (Source: Translation for Translators)
