John 1:21

21So they asked him, ‘So who are you? Are you Elijah?’

John said, ‘No, I am not.’

They asked, ‘Are you the Prophet?’

John answered, ‘No.’1:21 The Jews believed that God would send his prophet Elijah and at least one other great prophet to them. They believed that these prophets must come before God would send his Messiah.
