The phrases that are translated as “clean animals” and “unclean animals” in English: The first draft into Maan had “animals not cursed” and “cursed animals,” which did not express correctly the idea of ritually pure and impure animals. So it was changed to “animals accepted by God for sacrifices” and “animals not accepted by God for sacrifices.”

In Kwere it is translated as animals “which are eaten” vs. “which are not eaten”. (Source: Pioneer Bible Translators, project-specific translation notes in Paratext)
