Ex. xxviii. 19. & xxxix. 12.AMETHYST, a precious Stone, the ninth in place upon the High Priest’s Rational or Breast-plate. The colour of it comes near that of new wine, and goes off with a violet. It is said to prevent people’s getting drunk; that it is a defence against the effects of poison; and that it is a help to conception. The Hebrew name which the Septuagint translaté
and Vulgate Amethyst, is Achalma, which may signify Sleep. The Chaldee, Onkelos, and the Syriac, translate it Een-egla, or the Eye of a Calf. The name of Issachar was engraven on this Stone.
