And who is he, Lord, that I may believe on him? (Kai ti estin, kurie;). The initial kai (and) is common ( Mark 10:26 ; Luke 10:29 ; Luke 18:26 ). Probably by kurie he means only "Sir." It usually comes at the beginning of the sentence, not at the end as here and verse Luke 38 . That I may believe on him (ina pisteusw ei auton). Ellipsis to be supplied before this final clause. He catches up the words of Jesus in the preceding verse, though he does not yet know who the Son of Man (or Son of God) is, but he trusts Jesus.
