Stone
Stones in the Bible in general represent truths, or things we know concerning the Lord and what He wants from us and for us in life. This is why the people of Israel built altars of stone, and is also why stoning was a principal form of capital punishment (using truth to destroy falsity, or in the negative sense using falsity to destroy truth). It is also why precious stones are described in such detail on Aaron's breastplate and ephod, and also in the New Jerusalem in Revelation; precious stones represent true ideas directly from the Lord with the various colors showing various forms of love. Stones are not alone in representing truth, of course -- it sometimes seems that almost everything in the Bible represents either true ideas or desires for good. But that makes sense, since our thoughts and our desires together are everything we are in life, and the interplay between them is what life is all about. The many ways they are represented in the Bible reflect the incredible variety in our feelings and thoughts, though we can only distantly understand how those representations work. In the case of stones, in their weight, strength and permanence they tend to represent true ideas that come from a desire for good, the understanding we can have if we are truly good and loving -- and in the highest sense the exalted ideas that come from the Lord's love. Those ideas are ones that are not easily moved or changed, and make wonderful foundations for the things we want to build in our spiritual lives.
Daniel 7:3-7
3
Four great animals came up from the sea, diverse one from another.
4
The first was like a lion, and had eagle's wings: I saw until its wings were plucked, and it was lifted up from the earth, and made to stand on two feet as a man; and a man's heart was given to it.
5
Behold, another animal, a second, like a bear; and it was raised up on one side, and three ribs were in its mouth between its teeth: and they said thus to it, Arise, devour much flesh.
6
After this I saw, and behold, another, like a leopard, which had on its back four wings of a bird; the animal had also four heads; and dominion was given to it.
7
After this I saw in the night visions, and, behold, a fourth animal, awesome and powerful, and strong exceedingly; and it had great iron teeth; it devoured and broke in pieces, and stamped the residue with its feet: and it was diverse from all the animals that were before it; and it had ten horns.
