Matthew 17:9a, 10-13

Matthew 17:9a, 10-13
9 And as they were descending from the mountain,
10 And his disciples questioned him, saying, "Why then do the scribes say that it is necessary for Elijah to arrive first?"
11 But in response, he said to them: "Elijah, indeed, shall arrive and restore all things.
12 But I say to you, that Elijah has already arrived, and they did not recognize him, but they did whatever they wanted to him. So also shall the Son of man suffer from them."
13 Then the disciples understood that he had spoken to them about John the Baptist.
