'Pure' in the Bible

The words of Jehovah are pure words; As silver tried in a furnace on the earth, Purified seven times.

With the pure thou wilt show thyself pure; And with the perverse thou wilt show thyself froward.

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

He that hath clean hands, and a pure heart; Who hath not lifted up his soul unto falsehood, And hath not sworn deceitfully.

Surely God is good to Israel, Even to such as are pure in heart.

Thy word is very pure; Therefore thy servant loveth it.
