Arcana Coelestia#6121
6121. 'Give your livestock, and I will give you [bread] in exchange for your livestock' means that they were to offer forms of the good of truth and would be sustained. This is clear from the meaning of 'livestock' as forms of the good of truth, dealt with in 6016, 6045; and from the meaning of 'giving in exchange for them' - giving them bread - as the sustaining of spiritual life, dealt with above in 6118.

6118. 'Saying, Give us bread' means a plea for the sustainment of spiritual life. This is clear from the meaning of 'giving', when it has reference to 'bread', as sustaining; and from the meaning of 'bread' as spiritual life. In a specific sense 'bread' means the good of love and charity; but in a general sense it means spiritual life, for in this case bread is used to mean all food, as shown in 2165. When used to mean all food in general, it is spiritual life; for in the spiritual sense food in general is all the good of love and all the truth of faith. These two are what compose spiritual life.
