Following is a back-translations of 1 Samuel 15:21 from the translation in Aruamu: “We know that, the Ever Present God himself chose these sheep and cows for himself and told/commanded us for the purpose of killing them. And the fighting men got from amongst these animals some very good animals for the purpose of doing offering to your Ever Present God here at Gilgal and came.” (Source:Pioneer Bible Translators, project-specific translation notes in Paratext)
