Mark 6:18-20

New Catholic Bible

¹⁸ For John had told Herod, “It is unlawful for you to have your brother’s wife.”

¹⁹ As for Herodias, she was filled with resentment against John and wanted to have him killed, but she was unable to do so, ²⁰ because Herod was afraid of John, knowing him to be a holy and righteous man. Therefore, he protected him from harm. When he heard John speak, he was greatly perplexed by his words, but even so he liked to listen to him.
