What is man, that he may be clean? and how may the son of woman be upright?

Truly, he puts no faith in his holy ones, and the heavens are not clean in his eyes;

Though my hands have done no violent acts, and my prayer is clean.

Still the upright keeps on his way, and he who has clean hands gets new strength.

He makes safe the man who is free from sin, and if your hands are clean, salvation will be yours.

How then is it possible for man to be upright before God? or how may he be clean who is a son of woman?

I am clean, without sin; I am washed, and there is no evil in me:
