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 [of him], he said, It is John, whom I beheaded: he hath risen from the dead.

17 For Herod himself had sent forth and laid hold upon John, and bound him in prison for the sake of Herodias, his brother Philip's wife: for he had married her.

18 For John had said to Herod, It is not lawful for thee to have thy brother's wife.

19 Therefore Herodias had a quarrel against him, and would have killed him; but she could not:

20 For Herod feared John, knowing that he was a just and holy man, and observed him: and when he heard him, he did many things, and heard him gladly.
