156. Verse 23 And the man said, By this change, it is bone from my bones and flesh from my flesh; for this she will be called Wife, because she was taken out of man (vir).

'Bone from bones and flesh from flesh' means the proprium belonging to the external man, 'bone' the proprium that has been given not much life, 'flesh' the proprium that has been given life. 'The man' (vir) however means the internal man. And because, as is said in the next verse, the internal man was so coupled to the external man, this proprium previously called 'woman' is now called 'Wife'. 'By this change' means that it happened now, because there had been a change of state.

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.
