But Saul increased the more in strength, and confounded the Jews which dwelt at Damascus, proving that this is very Christ. Confounded the Jews - Συνεχυνε, Overwhelmed them so with his arguments that they were obliged to blush for the weakness of their own cause.
Proving that this - Οὑτος, This person, viz. Jesus, is very Christ; εϚιν ὁ ΧριϚος, Is the Christ, or Messiah. See on Acts 9:21 (note).
