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.
Arcana Coelestia #6045
6045. 'For they are keepers of livestock' means that they possess good deriving from truths. This is clear from the meaning of 'livestock' as the good of truth, which is good deriving from truths, dealt with in 6016. The description here has reference to the sons of Israel, by whom spiritual truths within the natural are represented, 5414, 5879, and so has reference to truths, here to the fact that they lead to good, regarding which see immediately above in 6044.
