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.

9625. 'And put the clasps into the loops' means the mode of the joining together. This is clear from the consideration that since an ability to join things together is meant by 'the clasps', dealt with immediately above in 9624, 'putting them into the loops' and thereby 'joining the curtains together' means the mode of the joining together, as is also meant above in 9612 by 'joining the curtains together, each one to the next by means of the clasps'.
