The word koosh in Hebrew means Black.
It is a Hebrew word.
Shachar also means Black.
Hebrew is a language of very few words and each word has various meanings depending on the context.
Using a "Heaven Breathed" English Christian Bible for the meaning of Hebrew words is ludicrous.
you are confusing butterfly. She seems to think that anything translated into the English word----BLACK----means the color of the black crayon in the Crayola box. Neither the word KUSH---or SHACHAR denote or connote the black
crayon
