Book of Mark - Chapter 6 - Verse 14
And king Herod heard of him; (for his name was spread abroad:) and he said, That John the Baptist was risen from the dead, and therefore mighty works do shew forth themselves in him.
Meaning
King Herod, upon hearing about Jesus, mistook him for John the Baptist whom he had beheaded earlier. The reputation of Jesus had spread far and wide, leading Herod to believe that John had come back to life in the person of Jesus. This misunderstanding fueled Herod's belief that Jesus was a powerful figure, capable of performing miraculous works due to his mistaken identity with John the Baptist. Herod's fear and guilt over John's death may have driven him to this conclusion, as he grappled with the consequences of his actions. This verse highlights the impact that Jesus had on those around him, prompting even those who had harmed his followers to take notice of his presence and teachings.
