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 this, he said, “John, whom I beheaded, has risen from the dead!”

17 For Herod himself had ordered that John be arrested and bound and imprisoned, on account of his brother Philip’s wife Herodias, whom Herod had married.

18 For John had been telling Herod, “It is not lawful for you to have your brother’s wife!”

19 So Herodias held a grudge against John and wanted to kill him. But she had been unable,

20 because Herod feared John and protected him, knowing that he was a righteous and holy man. When he heard John’s words, he was greatly perplexed; yet he listened to him gladly.
