Job 35:3

If you ask what it profits you: 'How do I benefit {by refraining from my sin}?'

Indeed, he says, 'A man does not profit when he takes delight in God.'

"I [am] blameless; I do not care about myself; I loathe my life.

If I wash myself with soap, and I cleanse my hands with lye,

If I am guilty, woe to me! But if I am righteous, I dare not lift my head; [I am] filled [with] shame, and [just] look [at] my misery!

Who [is] Shaddai that we should serve him, or what would we benefit when we plead with him?'

And what [is] the portion of God from above or the heritage of Shaddai from on high?

Surely in vain I have kept my heart pure, and washed my hands in innocence.

You have said, '[It is] useless to serve God! What [is the] gain if we keep his requirements, and if we walk as mourners {before} Yahweh of hosts?

For thou saidst, What advantage will it be unto thee? and, What profit shall I have, if I be cleansed from my sin?
