'Purest' in the Bible

the flowers, lamps, and gold tongs—of purest gold;

the wick trimmers, sprinkling basins, ladles, and firepans—of purest gold; and the entryway to the temple, its inner doors to the most holy place, and the doors of the temple sanctuary—of gold.

Since I love Your commandsmore than gold, even the purest gold,

His head is purest gold.His hair is wavyand black as a raven.
