NT.filter - rwp flashing:

rwp@Revelation:4:3 @{To look upon} (\horasei\). Locative case of \horasis\, old word (from \hora\, to see) for appearance (in appearance) as in strkjv@Ezekiel:1:5,26|. {Like a jasper stone} (\homoios iaspidi\). Associative-instrumental case of \iaspis\, old word (Persian), used for stones of different colors, one opaque like opal, one translucent (21:11,18f.|, possibly here, only N.T. examples), one a red or yellow stone (Isaiah:54:12|). Some even take it for the diamond. Certainly not our cheap modern jasper. {A sardius} (\sardii\). Old word, in N.T. only here and strkjv@21:20|. The carnelian or other red stone, derived from Sardis (Pliny). {Rainbow} (\iris\). Old word, in N.T. only here and strkjv@10:1|. From strkjv@Ezekiel:1:28|. {An emerald} (\smaragdini\). Adjective (from \smaragdos\, strkjv@Revelation:21:19|), of emerald (supply \lithi\), in associative instrumental case after \homoios\. John sees no form for God (Exodus:24:10|), but only the brilliant flashing gems. "In the vision the flashing lustre of the \iaspis\ and the fiery red of the \sard\ are relieved by the halo (\iris\) of emerald which encircled the Throne" (Swete). A complete circle.
