Mark 6:18 Meaning and Commentary

Mark 6:18

For John had said unto Herod
He had been personally with him, and had plainly and freely told him of his sin, and faithfully reproved him for it; alleging what he had done was contrary to the law of God:

it is not lawful, for thee to have thy brother's wife:
(See Gill on Matthew 14:4).

Mark 6:18 In-Context

16 But [when] Herod heard [it], he said, "John whom I beheaded--this one has been raised!"

17 For Herod himself had sent [and] arrested John and bound him in prison because of Herodias, the wife of Philip his brother, because he had married her.

18 For John had been saying to Herod, "It is not permitted for you to have your brother's wife."

19 So Herodias held a grudge against him and was wanting to kill him, and was not able [to do so].

20 For Herod was afraid of John, [because he] knew him [to be] a righteous and holy man and protected him. And [when he] listened to him, he was greatly perplexed, and [yet] he listened to him gladly.
