Too many Original Hebrews were thought to be Egyptians back in the day for them not to be black
Moses & Joseph were all mistaken for Egyptian and anyone with common sense knows that the Egyptians visually and scientifically were black people.
EGYPTIANS WERE A SHADE DARKER THAN THE JEWS BUT NOT DARK SKINNED BLACK .. THEY WERE THE COLOR OF ARRON AFFLALO, WHO INTETESTINGLY ENOUGH HAS A NAME WIT JEWISH ROOTS. ARRON AFFLALO COULD ACTUALLY BE MISTAKEN FOR A DARK SKINNED ISRAELI, IT IS NOT UNCOMMON FOR JEWS TO RANGE IN COLOR
