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 Which Herod hearing, said: John whom I beheaded, he is risen again from the dead.

17 For Herod himself had sent and apprehended John, and bound him prison for the sake of Herodias the wife of Philip his brother, because he had married her.

18 For John said to Herod: It is not lawful for thee to have thy brother’s wife.

19 Now Herodias laid snares for him: and was desirous to put him to death and could not.

20 For Herod feared John, knowing him to be a just and holy man: and kept him, and when he heard him, did many things: and he heard him willingly.
