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.

246. 'Beast' and 'wild animal of the field' mean affections. This becomes clear from what has been stated already in 45, 46, about 'beast' and 'wild animal', to which let the following quotation from David be added,

You shake down a shower of blessings, O God; Your heritage which is labouring, You strengthen; Your wild animals will dwell in it. Psalms 68:9-10.

Here also 'wild animal' stands for the affection for good, since it is going 'to dwell in God's heritage'. The reason 'beast' and 'wild animal of the field' are mentioned here, as also in Genesis 2:19, 20, but 'beast' and 'wild animal of the earth' in Genesis 1:24-25, is that the subject is the Church, that is, man when regenerate, whereas in Chapter 1 the subject is the time when the Church does not exist, that is, when man has yet to be regenerated; for 'field' is a term applying to the Church, that is, to man when regenerate.
