Following are a number of back-translations as well as a sample translation for translators of 2 Samuel 13:4:

• Kupsabiny: “One day, Jonadab told Amnon that, ‘Why is it that when it comes to morning/sunrise you always look miserable, and yet you are the son of a king? Please tell me what is wrong?’ Amnon replied that, ‘My head wants Tamar, who is the sister of Absalom.’” (Source: Kupsabiny Back Translation)
• Newari: “He said to Amnon, "O Prince! Why are you dejected like this every day, what has happened to you?
  Then Amnon said to him, "I have fallen very much in love with my brother Absalom’s younger sister, Tamar."” (Source: Newari Back Translation)
• Hiligaynon: “One day, he asked Amnon, ‘You (sing.) are a child of the king, but why (is it) that every day I always see you (sing.) being-weak/lit. cause-(yourself)-to-be-weak. Tell me please your problem.’ Amnon said to him, ‘I like/love/am-in-love-with Tamar, the sister of Absalom my brother from (the-side-of) father.’” (Source: Hiligaynon Back Translation)
• English: “One day Jonadab said to Amnon, ‘You are the king’s son, but every day I see that you seem very depressed/sad. What is your problem?’ Amnon replied, ‘I am in love/want to sleep with Tamar, my half-brother Absalom’s sister.’” (Source: Translation for Translators)
