O that one would hear me! O that I might have my cause heard by any just and impartial judge! Behold, my desires, &c. So the Vulgate and the Targum understand תוי, tavi, here, deriving it from אוה, ivvah, he desired, he coveted. Some, however, deriving it from תוה, tivvah, to mark, to design, to define, render the clause, Lo, here is my sign, mark, or pledge, namely, that I will stand the trial. But the former seems to be the true sense, and is approved by A. Ezra and R. Levi. That the Almighty would answer me Answer my desire herein, either by hearing me himself, or by appointing some impartial person to judge whether I be such a hypocrite as my friends make me, or an upright person. And that mine adversary Whosoever he be that shall contend with, or accuse me; had written a book Had put down in writing the charges he has against me, and brought them in. He alludes to what is usual in judicial proceedings. This shows that letters were in use in Job's time.
