Thou hast blinded the minds of my friends, that they can not see those truths which are most plain and evident to all men of sense and experience; therefore I desire a more wise and able judge. Therefore shalt thou not exalt them, i.e. thou wilt not give them the victory over me in this contest, but wilt give sentence for me, and discharge them, and make them ashamed of their confidence in affirming falsehoods of thee, and punish them severely for their miscarriage. It is a usual figure, whereby much more is understood than is expressed.
