'Judge' in the Bible

For though I were righteous, I could not answer.I must appeal for mercy to my Opponent and Judge.

“You say, ‘What does God know [about me]?Can He judge through the thick darkness?

“There the righteous and upright could reason with Him;So I would be acquitted forever by my Judge.

What then could I do when God arises [to judge me]?When He calls me to account, what will I answer Him?
