[9:37] 2 tn The καί – καί (kai – kai) construction would normally be translated “both – and”: “You have both seen him, and he is the one speaking with you.” In this instance the English semicolon was used instead because it produces a smoother and more emphatic effect in English.
[9:38] 3 sn Assuming the authenticity of John 9:38-39a (see the tc note following the bracket in v. 39), the man’s response after Jesus’ statement of v. 37 is extremely significant: He worshiped Jesus. In the Johannine context the word would connote its full sense: This was something due God alone. Note also that Jesus did not prevent the man from doing this. The verb προσκυνέω (proskunew) is used in John 4:20-25 of worshiping God, and again with the same sense in 12:20. This would be the only place in John’s Gospel where anyone is said to have worshiped Jesus using this term. As such, it forms the climax of the story of the man born blind, but the uniqueness of the concept of worshiping Jesus at this point in John's narrative (which reaches its ultimate climax in the confession of Thomas in John 20:28) may suggest it is too early for such a response and it represents a later scribal addition.
