4:3. And He that sat was to look upon like a jasper.—“And the building of the wall of it was of _jasper_: and the city was pure gold, like unto clear glass. And the foundations of the wall of the city were garnished with all manner of precious stones. The first foundation was _jasper_.” (Rev. 21:18, 19.) “A precious stone, variegated with divers colors, and of a very hard quality; some have been found of a sea‐green color.” (Diaglott note.) “The ancient _jasper_ thus appears to have been frequently translucent, but the modern is opaque.” (McC.) The jasper, therefore, is supposed to refer to the modern rare and beautiful green‐tinted diamond. The diamond is the hardest substance known, excelling in brilliancy and beautiful play of prismatic colors. The crystals of which it is composed are bounded by _eight_ equal equilateral triangles; _twenty‐four_ angles in all, constituting a perfect double pyramid, set base to base. How adorable, how sublime, how perfect is our God! How impossible to describe Him! To know Him aright will require eternity. The jasper seems especially to illustrate His glory, perfection and _prescience_. (He uses twenty‐four elders—prophecies.) And a sardine stone.—“The sard, which is a superior variety of agate, has long been a favorite stone for the engraver’s art. On this stone all the finest works of the most celebrated artists are to be found; and this not without good cause, such is its toughness, facility of working, beauty of color, and the high polish of which it is susceptible, and which it retains longer than any other gem. The sardius is the stone now called the carnelian, from its color, which resembles that of raw flesh. It is supposed to stop hemorrhage when laid on a fresh wound.” (McC.) The sardius seems especially to illustrate God’s love, His memory of His creatures, and His purpose of a resurrection for all smitten in Adam and redeemed in Christ. Will God forget to raise any of His blood‐bought? “Can a woman forget her sucking child, that she should not have compassion on the son of her womb? Yea, they may forget, yet will I not forget thee. Behold I have graven thee upon the palms of My hands.”—Isa. 49:15, 16.
