A garment of the entwinings of gold and of needlework, as in Psalm 45:13, signifies the Lord's divine truth.

A garment down to the foot, as in Revelation 1:13, signifies the leading divine which is divine truth.

It is said, in Deuteronomy 22:11, "Thou shalt not wear a garment of diverse sorts; as of woolen and linen together…”. This means that the states of good and truth should not be mixed up: people in the spiritual kingdom of the Lord cannot be also in His celestial kingdom at the same time, and vice versa.

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.
