Mark 6:22-23

Young's Literal Translation

²² and the daughter of that Herodias having come in, and having danced, and having pleased Herod and those reclining (at meat) with him, the king said to the damsel, `Ask of me whatever thou wilt, and I will give to thee,'

²³ and he sware to her -- `Whatever thou mayest ask me, I will give to thee -- unto the half of my kingdom.'
