The three gates on the east side (Ezek 48:32-48:32)

“On the east side,

It shall be  

Four thousand five hundred cubits.

The three gates are

The gate of Joseph,

The gate of Benjamin,

The gate of Dan.”

There were 3 gates on the east side, 4,500 cubits from the center. It is interesting to note that Manasseh and Ephraim are no longer mentioned but merely their father, Joseph, as if it was only one tribe. The sons clearly had land given to them. The gate of Joseph would have been the most popular, since Benjamin and Dan were smaller tribes.
