Fire, in the spiritual sense, can mean either love or hatred depending on the context, just as natural fire can be either comforting in keeping you warm, or scary in burning down your house. Our language reflects this, too -- we use concepts like a smoldering hatred or a burning love. So fire signifies a love, either a good love of the neighbor and to the Lord, or, in a bad sense, selfish love of oneself that, if unchecked by conscience, leads to hatred of anyone that opposes it.

8019. 'By their hosts' means those people made distinct from one another by the specific character of their good, which is derived from truth. This is clear from the meaning of 'hosts' as forms of good and truths, dealt with above in 7988. 'By hosts' means that those people, those who are represented by 'the children of Israel', were made distinct from one another by the specific character of their good, which is derived from truth; for all in the next life are made distinct from, yet are linked to one another by their varieties of good, see 7833-7836, 8003. The expression 'by the specific character of their good, which is derived from truth' is used because all good derives its specific character from truth, and is for that reason varied, 3804, 4149, 5345, 5355, 6916.
