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 Jesus answered, "Elijah is coming and will put everything in order again.

13 Then the disciples understood that he was talking about John the Baptizer.

14 When they came to a crowd, a man came up to Jesus, knelt in front of him,

15 and said, "Sir, have mercy on my son. He suffers from seizures. Often he falls into fire or water.
