Job 9:27-31

27If I say, ‘I will forget my complaint, I will change my expression, and smile,’

28I still dread all my sufferings, for I know you will not hold me innocent.

29Since I am already found guilty, why should I struggle in vain?

30Even if I washed myself with soap and my hands with cleansing powder,

31you would plunge me into a slime pit so that even my clothes would detest me.
