'Guards,' as in Genesis 37:36, signify things that minister. 'To guard,' when used as in Genesis 41:35, denotes 'to store up.'

(Odkazy: Arcana Coelestia 5298)

5298. 'And let them guard it' means to be stored away there. This is clear from the meaning of 'guarding' as storing away, that is to say, storing away in the interior parts of the natural mind, which are meant by 'cities', dealt with immediately above in 5297.
