Following are a number of back-translations as well as a sample translation for translators of 1 Samuel 25:39:

• Kupsabiny: “When David heard that Nabal was dead, he said that, ‘Glory be to God who fought for me and punished Nabal because of what he did to me. I also glorify God because he protected/prevented me from doing bad things. So, God alone/himself is the one who has paid back Nabal for the sin he did to me.’
  Then David sent some of his people to come and tell Abigail that he wants to marry her.” (Source: Kupsabiny Back Translation)
• Newari: “David heard that Nabal had died and he said, "May the LORD be praised! Because he made fun of me by slandering [me], He paid him back and saved me from doing wrong. The LORD poured out on his own head the wrong that Nabal did." Then by his own servants David sent the message to Abigail for her to marry him.” (Source: Newari Back Translation)
• Hiligaynon: “When David heard that Nabal died, he said, ‘Praise-be to the LORD! He is-the-one who has-avenged/has-paid-back Nabal for his insulting me, and he has-kept- me -away from avenging/paying-(him)-back. He has-punished Nabal for the evil which was-done to me.’
  Then David sent messengers to-ask/request Abigail that she be-married to him.” (Source: Hiligaynon Back Translation)
• English: “After David heard that Nabal was dead, he said, ‘Praise Yahweh! Nabal insulted me, but Yahweh vindicated me/got revenge for me. He has prevented me from doing anything wrong. And he has punished Nabal for the wrong that he did.’
  Then David sent messengers to Abigail, to ask her if she would become his wife.” (Source: Translation for Translators)
