Jua 9:37 Le dijo Jesús: Pues le has visto, y el que habla contigo, él es.
Jua 9:38 Y él dijo: Creo, Señor; y le adoró.
Jua 9:39 Dijo Jesús: Para juicio he venido yo a este mundo; para que los que no ven, vean, y los que ven, sean cegados.
Comentario de los traductores de la NET Bible en inglés (trinitarios):
110 tc ‡ Some early and important witnesses (Ì75 א* W b sams ac2 mf) lack the words, "He said, 'Lord, I believe,' and he worshiped him. Jesus said," (Joh_9:38-39 (i.e., John 9:38-39a)). This is weighty evidence for the omission of these words. It is difficult to overstate the value of Ì75 here, since it is the only currently available papyrus MS extant for the text of Joh_9:38-39. Further, א is an important and early Alexandrian witness for the omission. The versional testimony and Codex W also give strong support to the omission. Nearly all other MSS, however, include these words. The omission may have been occasioned by parablepsis (both Joh_9:37 and Joh_9:39 begin with "Jesus said to him"), though it is difficult to account for such an error across such a wide variety of witnesses. On the other hand, the longer reading appears to be motivated by liturgical concerns (so R. E. Brown, John [AB], 1:375), since the verb προσκυνέω (proskuneō, "I worship") is used in Joh_4:20-25 of worshiping God, and again with the same sense in Joh_12:20. If these words were authentic here, this would be the only place in John's Gospel where Jesus is the explicit object of προσκυνέω. Even if these words are not authentic, such an omission would nevertheless hardly diminish John's high Christology (cf. Joh_1:1; Joh_5:18-23; Joh_14:6-10; Joh_20:28), nor the implicit worship of him by Thomas (Joh_20:28). Nevertheless, a decision is difficult, and the included words may reflect a very early tradition about the blind man's response to Jesus.
Lo que dicen, es que una parte importante de ese texto, no figura en importantes manuscritos antiguos, y podría estar agregada.
Con lo cual el etxto quedaría:
Jua 9:37 Le dijo Jesús: Pues le has visto, y el que habla contigo, él es.
Jua 9:38 Y él dijo: Creo, Señor; y le adoró.
Jua 9:39 Dijo Jesús: Para juicio he venido yo a este mundo; para que los que no ven, vean, y los que ven, sean cegados.
Saludos.
