'Pure' in the Bible

The words of Jehovah are pure words, silver tried in the furnace of earth, purified seven times.

With the pure thou dost shew thyself pure; and with the perverse thou dost shew thyself contrary.

The precepts of Jehovah are right, rejoicing the heart; the commandment of Jehovah is pure, enlightening the eyes;

For thou hast met him with the blessings of goodness; thou hast set a crown of pure gold on his head.

He that hath blameless hands and a pure heart; who lifteth not up his soul unto vanity, nor sweareth deceitfully:

{A Psalm of Asaph.} Truly God is good to Israel, to such as are of a pure heart.

Thy word is exceeding pure, and thy servant loveth it.
