There are 4  gospels - Matthew1 Mark2 Luke3 John4
The 4th is also different than the other 3.

There are 4 dimensions:
Ephesians 3:18 KJV
May be able to comprehend with all saints what is the breadth1, and length2, and depth3, and height4;
Breadth, length and depth (an alternative word for height) are all 3 dimensional but the 4th is different.
