The North Gates
40:19-27


The area of X is comprised, by deduction from the known distances, of a rectangle which measures 100 by 300 in length. This rectangle is subdivided into three parts, each being 100 cubits square. The area of X contains 1.) the altar with its court, 2.) the temple and its own court, and 3.) the building to the west with its court.

This information -- as proof -- is revealed later on in the prophetic vision.
