In the context, the prophet contrasts the unrighteousness of those who used the labor of others without pay, with the justice and equity practiced by their patriarchal ancestor toward the poor.

Now Christ being the way to the Father, both as to justification, in taking away the enmity, in changing our state, and removing our unrighteousness and guilt, whereby we were lying under the sentence of the law, adjudging such sinners as we are to hell; and as to sanctification, in cleansing us from all our pollutions, renewing our souls, washing away our spots and defilements, &c. He must be made use of in reference to both.

[Sidenote: Job 26:1, 27:2, 4, 5] Then Job answered and said, As God liveth, who hath taken away my right, And the Almighty, who hath made my life bitter, Surely my lips do not speak unrighteousness, Nor does my tongue utter falsehood, Far be it from me that I should grant that you are right; Until I die I will not give up my innocence.

Because He is righteous He will not suffer your unrighteousness.
