Let me be weighed in an even balance
Or "in balances of righteousness" F26, even in the balance or strict justice, the justice of God; he was so conscious to himself that he had done no injustice to any man in his dealings with them, that, if weight of righteousness, which was to be, and was the rule of his conduct between man and man, was put into one scale, and his actions into another, the balance would be even, there would be nothing wanting, or, however, that would require any severe censure:
that God may know mine integrity;
God did knew his integrity, and bore a testimony to it, and to his retaining it, ( Job 2:3 ) ; but his meaning is, that should God strictly inquire into his life and conduct with respect to his dealings with men, as it would appear that he had lived in all good conscience to that day, so he doubted not but he would find his integrity such, that he would own and acknowledge it, approve of it, and commend it, and make it known to his friends and others, whereby he would be cleared of all those calumnies that were cast upon him. Some connect these words with the following, reading them affirmatively, "God knows mine integrity"; he knows that my step has not turned out of the way of truth and righteousness; that my heart has not walked after mine eye, in lustful thoughts and desires; and that there is no spoil, nor rapine, nor violence in my hand, that I should deserve such a punishment as to sow, and another eat: thus Sephorno.
