(Heb yashpheh, "glittering"), a gem of various colours, one of the twelve inserted in the high priest's breast-plate (Ex 28:20). It is named in the building of the New Jerusalem (Re 21:18-19). It was "most precious," "clear as crystal" (Re 21:11). It was emblematic of the glory of God (Re 4:3).
Last of the gems in the high priest's breast-plate (Ex 28:20), probably the green jasper. In Re 21:19 it is first of New Jerusalem's foundations. It represents watery crystalline brightness, symbol of purity: Re 21:11, "her light was like unto a stone most precious, even like a jasper stone, clear as crystal." "He that sat upon the throne (Re 4:3) was to look upon like a jasper." Ebrard thinks the diamond is meant. The common jasper has various wavy colors, somewhat transparent. The king of Tyre (Eze 28:13) has the jasper with eight other of the high-priest's 12 precious stones, as type of antichrist who usurps Christ's high-priesthood combined with kingship (Zec 6:13).
yashepheh, aspi" -->??????. This is not considered to be the same as the modern jasper, which is an opaque variety of quartz of many different colours. To what gem scripture refers is not known: some suppose the diamond. In Re 21:11 it is described as 'clear as crystal.' It had a place in the high priest's breastplate, and was one of the stones in the covering of the symbolical king of Tyrus in Eden. Ex 28:20; 39:13; Eze 28:13. He who sat on the throne in heaven, as seen by John, was 'to look upon like a jasper;' it is also used in the description of the heavenly Jerusalem. Re 4:3; Rev.21:11, 18, 19. The jasper is a symbol of the communicable glory of God. Compare Joh 17:22.
a precious stone frequently noticed in Scripture. It was the last of the twelve inserted in the high priest's breastplate,
and the first of the twelve used in the foundations of the new Jerusalem.
The characteristics of the stone as far as they are specified in Scripture,
are that it "was most precious," and "like crystal;" we may also infer from
that it was a stone of brilliant and transparent light. The stone which we name "jasper" does not accord with this description. There can be no doubt that the diamond would more adequately answer to the description in the book of Revelation.
JASPER, ????, Ex 28:20; 39:13; and Eze 28:13; ??????, Re 4:3; 21:11,18-19. The Greek and Latin name, jaspis, as well as the English jasper, is plainly derived from the Hebrew, and leaves little room to doubt what species of gem is meant by the original word. The jasper is usually defined, a hard stone, of a bright, beautiful, green colour; sometimes clouded with white, and spotted with red or yellow.
