Following are a number of back-translations as well as a sample translation for translators of 1 Samuel 29:3:

• Kupsabiny: “And/But when the other Philistine kings saw David coming with his people, they asked Achish that, ‘What are these Hebrews doing here?’ Achish replied that, ‘But this is David who was the assistant to Saul, that king of Israel. We have stayed with him for a long period of more than one year, and I have never seen any bad thing with him since the day he came to me.” (Source: Kupsabiny Back Translation)
• Newari: “But the Philistine commanders asked, "What are these Hebrews coming here to do?"
  Achish replied, "This is David the servant of Saul, king of Israel, He has been living with me for more than a year. Ever since he [came to] live with me until today I have not seen any guilt in him."” (Source: Newari Back Translation)
• Hiligaynon: “But the commanders of the Filistinhon asked Akish, ‘What are- these Hebrews -doing here?’ Akish replied, ‘That man is David the official of Saul the king of Israel. He has- already -been-with me for over one year, and starting when he left Saul until now I have-found nothing bad/wrong in him.’” (Source: Hiligaynon Back Translation)
• English: “But the Philistia commanders asked, ‘What are these Hebrews doing here, marching with us to battle?’
