Following are a number of back-translations as well as a sample translation for translators of 2 Samuel 18:33:

• Kupsabiny: “When David heard those words, he became very fearful and went to the upper room which was on the gate house crying for his son that, ‘Oh, oh, my son! My son Absalom so you have indeed died, oh no! It was better if I died and you remained, my son Absalom, oh, really!’” (Source: Kupsabiny Back Translation)
• Newari: “Then the king, his heart bursting with grief, weeping and weeping went up to the room above the main gate, speaking and speaking like this,
  "My child! my son Absalom, my son Absalom! My son Absalom,
  if only I had died instead of you!
  Oh Absalom, my son, my son!” (Source: Newari Back Translation)
• Hiligaynon: “David trembled. He went-up to the room above the entrance/gate of the town and cried-out/wept. While he was-going-up, he said, ‘O Absalom, my child, wish I had-died instead of you. O Absalom, my child, my child!’” (Source: Hiligaynon Back Translation)
• English: “The king realized that he meant that Absalom was dead, so he became extremely distressed/overcome with grief, and he went up to the room above the gateway and cried. While he was going up, he kept crying out, ‘O, my son Absalom! My son! O, my son Absalom, I desire/wish that I had died instead of you!’” (Source: Translation for Translators)
