'Jewels' in the Bible

Hezekiah was pleased and showed them his treasure house—the silver, the gold, the spices, the precious oil, his entire armory and everything that was found in his treasuries. There was nothing in his house nor in all his area of dominion that Hezekiah did not show them.

I will rejoice greatly in the Lord,My soul will exult in my God;For He has clothed me with garments of salvation,He has covered me with a robe of righteousness,As a bridegroom puts on a turban,And as a bride adorns herself with her jewels.
