Mark 6:18-20

Young's Literal Translation

¹⁸ for John said to Herod -- `It is not lawful to thee to have the wife of thy brother;'

¹⁹ and Herodias was having a quarrel with him, and was willing to kill him, and was not able,

²⁰ for Herod was fearing John, knowing him a man righteous and holy, and was keeping watch over him, and having heard him, was doing many things, and hearing him gladly.
