The length of one curtain shall be twenty eight cubits
 Or fourteen yards: 
 and the breadth of one curtain four cubits;
 or two yards; according to the common notion of a cubit being half a yard; but if, as Dr. Cumberland says, the Jewish and Egyptian cubit was three inches longer, this will make a considerable difference in the length and breadth of those curtains, especially in the former: 
 and everyone of the curtains shall have one measure;
 be of equal length and breadth.
