Verses 7-9 “7Now Herod the tetrarch heard of all that was done by him: and he was perplexed, because that it was said of some, that John was risen from the dead;
8And of some, that Elias had appeared; and of others, that one of the old prophets was risen again.
9And Herod said, John have I beheaded: but who is this, of whom I hear such things? And he desired to see him.”

Herod had a bad conscience!  He had beheaded John the Baptist and it had left him shaken.  Perhaps he suspected that his sins would find him out.  When he heard about Jesus’ miraculous deeds and powerful words, Herod began to think, “Is it John, risen from the dead?  Is it Elijah (some people said that he would come back)?  Maybe it is one of the old dead prophets.”  Note that every possibility considered by Herod would have involved a resurrection!  Herod knew that in order for Jesus to do the miraculous things He did, He would have to have resurrection power.  Jesus did arise from the dead, proving that He is able to do anything.
