Matthew Poole and continuators on John 5:31

31 If I bear witness of my self, my witness is not true .

This seemeth to contradict what he saith, Ch. 8.14. Tho I bear record of my self, yet my record is true: But our Saviour here speaketh according to the common Opinion of the Iews, or indeed of men, who are ready to suspect any ones Testimony, who testifieth of himself: He tells them, he could grant them this, tho his Record of himself was true, yet he could allow them their common received Opinion, and saying, Ch. 8.13. That the Testimony of one testifying of himself, is suspicious; for it is certain that a man may testifie truth of himself, onely such a testimony is suspicious; he tells them, he did not onely testifie of himself, his Reputation did not stand upon his own single word.
