'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,

My fruit is better than gold, better than even refined gold, and my benefit surpasses the purest silver.

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

For we are not like many, [acting like merchants] peddling God’s word [shortchanging and adulterating God’s message]; but from pure [uncompromised] motives, as [commissioned and sent] from God, we speak [His message] in Christ in the sight of God.
