Mark 6:18-20

YLT(i) 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.
