'Clean' in the Bible

The LORD will reward me because I am righteous; because my hands are clean he will restore me;

So the LORD restored me according to my righteousness, because my hands were clean in his sight.

The fear of the LORD is clean, standing forever. The judgments of the LORD are true; they are altogether righteous.

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

I kept my heart pure for nothing and kept my hands clean from guilt.
