Revelation 4:3

“And he that sat was to look upon like a jasper, etc.] For the brightness, glory, and majesty of his countenance, and for his being light itself, clothed with it, and dwelling in it; (see <662111>Revelation 21:11,18,19); and for the various perfections of his nature, as eternity, infinity, immutability, omniscience, omnipotence, omnipresence, wisdom, power, goodness, truth, love, grace, and mercy; for the jasper, at least one sort of them, is of various colours, and spotted with divers spots; that which is most valued is the green, spotted with red or purple f128: hence this stone, which is the twelfth in the high priest's breastplate, and on which the name of “Benjamin” was written, is…”

“was--omitted in the two oldest manuscripts but supported by Vulgate and Coptic. to look upon--Greek, "in sight," or "appearance." jasper--From Rev 21:11, where it is called most precious, which the jasper was not, EBRARD infers it was a diamond. Ordinarily, the jasper is a stone of various wavy colors, somewhat transparent: in Rev 21:11 it represents watery crystalline brightness. The sardine, our cornelian, or else a fiery red. As the watery brightness represents God's holiness, so the fiery red His justice executing fiery wrath. The same union of white or watery brightness and fiery redness appears in Rev 1:14; Rev 10:1; Eze 1:4; Eze 8:2; Dan 7:9. rainbow round about the throne--forming a…”

“And he that sat was to look upon - Was in appearance; or, as I looked upon him, this seemed to be his appearance. He does not describe his form, but his splendor. Like a jasper - ἰάσπιδι iaspidi The jasper, properly, is “an opaque, impure variety of quartz, of red, yellow, and also of some dull colors, breaking with a smooth surface. It admits of a high polish, and is used for vases, seals, snuff-boxes, etc. When the colors are in stripes or bands, it is called striped jasper” (Dana, in Webster’s Dictionary). The color here is not designated, whether red or yellow. As the red was, however, the common color worn by princes, it is probable that that was the color that appeared, and that John…”

“And he that sat was in appearance - Shone with a visible lustre, like that of sparkling precious stones, such as those which were of old on the high priest's breastplate, and those placed as the foundations of the new Jerusalem, Rev 21:19-20. If there is anything emblematical in the colours of these stones, possibly the jasper, which is transparent and of a glittering white, with an intermixture of beautiful colours, may be a symbol of God's purity, with various other perfections, which shine in all his dispensations. The sardine stone, of a blood - red colour, may be an emblem of his justice, and the vengeance he was about to execute on his enemies. An emerald, being green, may betoken…”

“4:3 Rather than painting a visual picture of God (Exod 20:4; Deut 4:15-19), John uses gemstones and the rainbow (Gen 9:8-17; Ezek 1:28) to suggest God’s qualities. The rainbow speaks of God’s grace as it recalls God’s covenant with Noah (Gen 9:13-17) that he would never again destroy the earth with water. In Revelation, however, we see the earth destroyed by fire (cp. Gen 19:24-29).”
