'Clean' in the Bible

The fear of Yahweh is clean, enduring forever. Yahweh's ordinances are true, and righteous altogether.

He who has clean hands and a pure heart; who has not lifted up his soul to falsehood, and has not sworn deceitfully.

Purify me with hyssop, and I will be clean. Wash me, and I will be whiter than snow.

Create in me a clean heart, O God. Renew a right spirit within me.
