Sapphire. (Hebrew, sappir). A precious stone, apparently of a bright-blue color, Exodus 24:10; set as the second stone, in the second row, of the high priest's breastplate, Exodus 28:18; extremely precious, Job 28:16. It was one of the precious stones, that ornamented the king of Tyre. Ezekiel 28:13. The sapphire of the ancients was not our gem of that name, namely, the azure or indigo-blue, crystalline variety of corundum, but our lapis lazuli (ultra-marine).
