the fifth was sardonyx [i.e., an orange-colored stone similar to chalcedony]; the sixth was sardius [i.e., a reddish-colored stone also called carnelian]; the seventh was chrysolite [i.e., a yellowish- or greenish-colored stone]; the eighth was beryl [i.e., a stone of bluish-green color]; the ninth was topaz [i.e., a yellow or bluish-yellow stone]; the tenth was chrysoprase [i.e., a stone of greenish-gold color]; the eleventh was jacinth [i.e., a stone of purple or reddish-blue color]; the twelfth was amethyst [i.e., a purple- or violet-colored stone].

And His feet were like shiny brass, [glowing] as when it is being refined in a furnace, and His voice was like the sound of much rushing water.

And I saw another mighty angel coming down from heaven. He was covered by a cloud and there was a rainbow above his head. His face was like the sun and his legs were like pillars of fire.

and he called out in a loud voice, like a roaring lion. And when he shouted, the seven thunders responded to the voice [of the angel]. [Note: These "seven thunders" have not been previously mentioned].
