The phrase that is translated as “the crops white (or: ripe) for harvest” in English is translated in Hiri Motu as “the crops are ripe and big and ready to eat.” The word for “ripe” hints at bananas and the word for “big” hints at sweet potatoes.
In Chokwe the white seed “mystified the reader (…) Ripe harvest-ready grains is ‘red,’ which in this land of few colour distinction is about the equivalent of ‘golden.’ To make send for the passage we felt justification in changing ‘white’ to ‘red.'” (Source: D. B. Long in The Bible Translator 1952, p. 87ff.)
