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 him, saying, Why do the scribes say that Elijah must first come?
12 And he answered and told them, Elijah verily shall come first and restore all things and how it is written of the Son of man, that he must suffer many things and be esteemed as nothing.
13 But I say unto you, That Elijah has indeed come, and they have done unto him whatsoever they wished, as it is written of him.
14 And as he came to the disciples, he saw a great multitude about them and scribes that disputed with them.
15 And straightway all the people, when they beheld him, were greatly amazed, and running to him saluted him.
