(Heb. sappir), a precious stone, apparently of a bright-blue color, set: (Exodus 24:10) 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, viz. the azure or indigo-blue, crystalline variety of corundum, but our lapis lazuli (ultra-marine).
