Fire
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.
Ezekiel 19:12-14
12
But it was plucked up in fury, it was cast down to the ground, and the east wind dried up its fruit: its strong rods were broken off and withered; the fire consumed them.
13
Now it is planted in the wilderness, in a dry and thirsty land.
14
Fire is gone out of the rods of its branches, it has devoured its fruit, so that there is in it no strong rod to be a scepter to rule. This is a lamentation, and shall be for a lamentation.
