The Greek in Mark 4:38 that is translated as “on a cushion” in English had to be more specific in Quetzaltepec Mixe and is translated as “with his head on the cushion.”
“Cushion” is translated in Acoli as laten-wic and in Lango as aten wic, both meaning “head support” or “pillow.” (Source: Mildred Brown in The Bible Translator 1960, p. 31ff. )
