Mark 6:19 (KJV)

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.

Others said, That it is Elias. And others said, That it is a prophet, or as one of the prophets.

But when Herod heard thereof, he said, It is John, whom I beheaded: he is risen from the dead.

For Herod himself had sent forth and laid hold upon John, and bound him in prison for Herodias' sake, his brother Philip's wife: for he had married her.

For John had said unto Herod, It is not lawful for thee to have thy brother's wife.

For Herod feared John, knowing that he was a just man and an holy, and observed him; and when he heard him, he did many things, and heard him gladly.

And when a convenient day was come, that Herod on his birthday made a supper to his lords, high captains, and chief estates of Galilee;

And when the daughter of the said Herodias came in, and danced, and pleased Herod and them that sat with him, the king said unto the damsel, Ask of me whatsoever thou wilt, and I will give it thee.

And he sware unto her, Whatsoever thou shalt ask of me, I will give it thee, unto the half of my kingdom.

And she went forth, and said unto her mother, What shall I ask? And she said, The head of John the Baptist.
