An adjective describing a dark brown or black coloring, appearing only in the Jacob-Laban flock narrative of Genesis 30. Jacob proposes to separate out every dark-colored lamb as his wages, using this word to mark the distinction between light and dark animals. The term is strikingly specific — it never appears outside this pastoral context. German braun ('brown') and Spanish oscuro ('dark') both reflect the earthy, natural-color sense rather than the moral darkness often conveyed by other Hebrew dark-words.
