Four
The number "four" in the Bible represents things being linked together or joined. This is partly because four is two times two, and two represents the ultimate linking between our desire to be good and our understanding of truth. We can also see this in the fact that most buildings are rectangular, with the four sides linking together to make a whole. We also divide directions into four -- north, east, south and west -- and talk about the "four corners" of something meaning all of it. So our special thinking naturally looks at four sides as linking together into a whole.

Arcana Coelestia # 9488
9488. 'And a cubit and a half its breadth' means what is complete so far as truth is concerned. This is clear from the meaning of 'one and a half' as what is complete, the reason why this number means what is complete being that 'three' has this meaning (for the half of a number is similar in meaning to the whole number, because a number that results from multiplication keeps the same meaning as a simple number of which it is the product through multiplication, 5291, 5335. Regarding 'three', that it means what is complete, see 2788, 7715, 9198; and that all numbers in the Word mean spiritual realities, 482, 487, 575, 647, 648, 755, 813, 1963, 1988, 2075, 2252, 3252, 4264, 4495, 4670, 5265, 5291, 5335, 5708, 6175, 7973); and from the meaning of 'breadth' as truth, dealt with immediately above in 9487.
