Matthew 17:13 Meaning and Commentary

Matthew 17:13

Then the disciples understood
By his saying that Elias was come, and by the account he gave of his ill usage, it was clear to them,

that he spake unto them of John the Baptist;
and that he was the Elias that was to come, and was come: so that this observation, that according to prophecy Elias was to come before the Messiah, was no objection to Jesus being the Messiah; but on the contrary, since he that was intended by Elias was come, and had done his work and office, it was a confirmation of the truth of his Messiahship.

Matthew 17:13 In-Context

11 And he answering said to them, Elias indeed comes first and will restore all things.
12 But I say unto you that Elias has already come, and they have not known him, but have done unto him whatever they would. Thus also the Son of man is about to suffer from them.
13 Then the disciples understood that he spoke to them of John the baptist.
14 And when they came to the crowd, a man came to him, falling on his knees before him, and saying,
15 Lord, have mercy on my son, for he is lunatic, and suffers sorely; for often he falls into the fire and often into the water.
