Arcana Coelestia #246
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.

493. There is no need to pause too long over the consideration that 'days' and 'years mean periods of time and states. Only this need be stated here, that in the world periods of time and measurements to which numbers may be applied are indispensable, for they belong within the ultimate realms of nature. But whenever such application occurs, the numbers of days and years, and also the numbers applied to measurements, mean something which is completely different from periods of time or from measurements, and which is determined by the meaning of the number used, as in the statements about there being six days for work, and the seventh being holy, which are dealt with above; in the statement about a jubilee having to be announced every forty-ninth year and celebrated in the fiftieth; about the tribes of Israel being twelve, the same number as the Lord's Apostles; and about there being seventy elders, the same number as the Lord's disciples. And there are many other examples where the numbers mean some special characteristic completely different from the persons or objects to which they apply. And when completely separated one from the other the states meant by the numbers are then left.
