Matthew 17:9a, 10-13
Chapter 17
9
And as they came down the mountain, Jesus commanded them not to tell anyone what they had seen until the Son of Man is raised from the dead.
10
The disciples asked him, “Why do the teachers of the law say that Elijah must come first?”
11
Jesus answered, “So it is: first comes Elijah; and he will restore all things.
12
But I tell you, Elijah has already come and they did not recognize him; and they treated him as they pleased. And they will also make the Son of Man suffer.”
13
Then the disciples understood that Jesus was referring to John the Baptist.
