Mark 9:13 Meaning and Commentary

Mark 9:13

But I say unto you, that Elias is indeed come
Meaning John the Baptist, who in prophecy is designed by him.

And they have done unto him whatsoever they listed;
(See Gill on Matthew 17:12); which words should be read in a parenthesis, as they are in the Vulgate Latin version; for what follows, as

it is written of him,
respects not what the Scribes and Pharisees, and the people of the Jews did to John at their pleasure; despising his ministry and message, rejecting the counsel of God delivered by him, and remaining impenitent and unbelieving, notwithstanding his powerful and awakening ministry, with many other things, which are no where written of him; but the words regard his coming, and the prophecies concerning him, and particularly, that under the name of Elijah, in ( Malachi 4:5 ) and which had had their accomplishment.

Mark 9:13 In-Context

11 And they asked Jesus, "Why do the teachers of the Law say that Elijah has to come first?"
12 His answer was, "Elijah is indeed coming first in order to get everything ready. Yet why do the Scriptures say that the Son of Man will suffer much and be rejected?
13 I tell you, however, that Elijah has already come and that people treated him just as they pleased, as the Scriptures say about him."
14 When they joined the rest of the disciples, they saw a large crowd around them and some teachers of the Law arguing with them.
15 When the people saw Jesus, they were greatly surprised, and ran to him and greeted him.
