Matthew 17
10 Ref And his disciples, questioning him, said, Why then do the scribes say that Elijah has to come first?
11 Ref And in answer he said, Elijah truly has to come and put all things right:
12 Ref But I say to you that Elijah has come, and they had no knowledge of him, but did to him whatever they were pleased to do; the same will the Son of man undergo at their hands.
13 Ref Then the disciples saw that he was talking to them of John the Baptist.
