Oh that one would hear me! Oh that I might have my cause heard by any just and impartial judge! That the Almighty would answer me, i.e. answer my desire herein; either by hearing me himself, or by appointing some indifferent person to judge whether I be such a hypocrite as my friends make me, or an upright person, and whether I have not cause to complain. Mine adversary; whosoever he be that shall contend with me, or accuse me, God himself not excepted, nay, possibly being chiefly intended, though for reverence to him he forbore to express it. So this is another of Job's irreverent and presumptuous expressions, for which he is so sharply reproved afterwards. Had written a book, i.e. had given me his charge written in a book or paper, as the manner was in judicial proceedings, that I might put in my answer into the court, which I am ready to do.
