9 As they went back down the mountain, Jesus commanded them, "Don’t tell anyone what you have seen until the Son of Man17:9 "Son of Man" is a title Jesus used for himself.has been raised from the dead."
10 Then his disciples asked him, "Why do the teachers of religious law insist that Elijah must return before the Messiah comes?17:10 Greek that Elijah must come first?"
11 Jesus replied, "Elijah is indeed coming first to get everything ready.12 But I tell you, Elijah has already come, but he wasn’t recognized, and they chose to abuse him. And in the same way they will also make the Son of Man suffer."13 Then the disciples realized he was talking about John the Baptist.
