SEV Biblia, Chapter 8:13
Entonces los fariseos le dijeron: T de ti mismo das testimonio; tu testimonio no es verdadero.
Clarke's Bible Commentary - John 8:13
Verse 13. Thou bearest record] As if they had said, Dost thou imagine that we shall believe thee, in a matter so important, on thy bare assertion? Had these people attended to the teaching and miracles of Christ, they would have seen that his pretensions to the Messiahship were supported by the most irrefragable testimony.
John Gill's Bible Commentary
Ver. 13. The Pharisees therefore said unto him , etc.] On account of his declaring himself the light of the world: these were either the same who went out of the temple, filled with remorse of conscience, and were now returned, and bearing him a grudge, came to take some advantage against him, if they could; or they were others of the same complexion, sent by them, to make their observations on him: thou bearest record of thyself . The Ethiopic version renders it, dost thou thyself? which does not seem so decent and comely; (see Proverbs 27:2); though it does not follow, that what a man says of himself is not truth, as these suggest: thy record is not true ; for John testified of himself, that he was not the Christ, nor Elias, nor that prophet; but the voice of one crying in the wilderness; and this testimony he bore of himself, at the importunity of the Jews themselves, ( John 1:19-23); and his testimony was true; so was that which Christ bore of himself; but their sense rather seems to be, that it was not firm and authentic, and would not pass in any court of judicature, since no man can be a witness in his own cause.
Matthew Henry Commentary
Verses 12-16 - Christ is the Light of the world. God is light, and Christ is the imag of the invisible God. One sun enlightens the whole world; so does on Christ, and there needs no more. What a dark dungeon would the world be without the sun! So would it be without Jesus, by whom light came int the world. Those who follow Christ shall not walk in darkness. The shall not be left without the truths which are necessary to keep the from destroying error, and the directions in the way of duty, necessar to keep them from condemning sin.

Vincent's NT Word Studies
13. Thou barest record of thyself. Rev., witness. A technical objection, evading the real purport of Jesus' declaration. The Rabbinical writings declared that no man could give witness for himself.
