Behold, there were four wheels beside the cherubs; the appearance of the wheels was like that of tarshish stone. Ezek 1:16; 10:9.

The cherubs' wheels are similar in meaning to a person's arms and feet, which is the power to act and go forward, this power being that of truth springing from good, see 8215. This explains why the appearance of those wheels was like that of tarshish stone; for 'tarshish' means truth springing from spiritual good, which possesses power.

[2] In Daniel,

I lifted up my eyes and saw, and behold, a man clothed in linen whose loins were girded with gold of Uphaz, and his body was like tarshish; and his face was like [the appearance] of lightning, and his eyes were like fiery torches. Dan 10:5, 6.

'A man clothed in linen' was an angel from heaven. 'Linen' means truth that is the clothing of good, 7601. By 'loins' conjugial love, which belongs to goodness and truth, is meant, 3021, 4280, 5050-5062. This is why the man's loins are said to have been 'girded with gold of Uphaz', for 'gold' means the good of love, 113, 1551, 1552, 5658, 9490, 9510. 'The body' however, by virtue of its correspondence, means the good of celestial love and also the good of spiritual love, 6135, while the surface of the body means the truth that springs from that good, which is why the man's body looked like tarshish. So it is that 'tarshish' means the truth that spiritual love desires.

[3] For the meaning of a shoham, the second stone in this row, as the truths of faith that spring from love, see what has been shown in 9476, 9841. As for a jasper, the third and last stone belonging to this row, that it means the truth of faith, this is clear in John's Revelation,

The light of the city, the holy Jerusalem, was like a most precious stone, as if it were a jasper stone, shining like crystal. Rev 21:11.

'The holy Jerusalem' means the Church that is going to take the place of the one that is ours at the present day. Its 'light' is the truth of faith and resulting intelligence, 9548, 9551, 9555, 9558, 9561, 9684. Therefore it is likened to 'a jasper stone, shining like crystal'. 'Crystal' as well means the truth of faith springing from good, in the same book,

The construction of the wall of the holy Jerusalem was jasper, and the city was pure gold, like pure glass. Rev 21:18.

The wall of the city is described as jasper because 'the wall' means the truth of faith protecting the Church, 6419. And since 'the wall' has this meaning, verse 19 of that chapter says that the first stone constituting its foundations was jasper. For by 'foundation' is meant the truth of faith springing from good, see 9643.
