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 were questioning him, saying, that the scribes say that Elijah it behoveth to come first.
12 And he answering said to them, `Elijah indeed, having come first, doth restore all things; and how hath it been written concerning the Son of Man, that many things he may suffer, and be set at nought?
13 But I say to you, That also Elijah hath come, and they did to him what they willed, as it hath been written of him.'
14 And having come unto the disciples, he saw a great multitude about them, and scribes questioning with them,
15 and immediately, all the multitude having seen him, were amazed, and running near, were saluting him.
