מִ֤י יִתֶּן־לִ֨י ׀ שֹׁ֘מֵ֤עַֽ לִ֗י הֶן־תָּ֭וִי שַׁדַּ֣י יַעֲנֵ֑נִי וְסֵ֥פֶר כָּ֝תַ֗ב אִ֣ישׁ רִיבִֽי׃
Oh that I had one to hear me!— Lo, here is my signature, let the Almighty answer me— And that I had the indictment which mine adversary hath written!
Rashi on Job
behold my inscription; may the Almighty bear witness for me Would that the Omnipresent bear witness for me in judgment, as He wrote concerning me (1:8): “For there is none like him on earth, a sincere and upright man, God-fearing.” Also Moses, who wrote his Book and my Book, will bear witness concerning me. (Another explanation:) This is what Job says, “Give it to inscribe me and my virtue.”
Malbim on Job
Pointing to the sores on his body, Job demands to know if they are really God’s handiwork.
