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 these rumors, he said, "John, whom I beheaded, has been raised to life."

17 He said this because Herod himself had arranged to have John arrested and put in prison because of Herodias, the wife of Herod's brother Philip. Herod had married her,

18 but John told Herod, "It's against the law for you to marry your brother's wife!"

19 So Herodias had it in for John. She wanted to kill him, but she couldn't.

20 This was because Herod respected John. He regarded him as a righteous and holy person, so he protected him. John's words greatly confused Herod, yet he enjoyed listening to him.
