Arcana Coelestia # 6721
6721. 'And hid him three months' means a complete period of time in which it was not seen. This is clear from the meaning of 'being hidden' as not being seen; and from the meaning of 'three months' as a complete period of time and a complete state. For the meaning of 'three' as what is complete, or an entire period from start to finish, see 2788, 4495. 'A month', like 'a day' or 'a year', means a period of time and a state, 2788; consequently a new state is meant by 'three months', 4901.

4010. 'And he put three days' journey between himself and Jacob' means that their state was one in which they were totally set apart. This is clear from the meaning of 'putting a journey' as being set apart; from the meaning of 'three' as that which is last, completed, or the end, dealt with in 1825, 2788, and so is totally set apart; and from the meaning of 'days' as states, dealt with in 23, 487, 488, 493, 893, 2788, 3462.
