Matthew Poole and continuators on Matthew 14:7

7 Whereupon he promised with an oath to give her whatsoever she would ask.

Mark relateth this more fully, but the Sense is the same, Ch. 6. v. 21, 22, 23. And when a convenient day was come, that Herod on his Birth-day 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 sate with him, the King said unto the Damsel: Ask of me whatsoever tho[illegible: 1 letter] 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. Those who have got over the point of Lawfulness in an Action, have nothing to Consult, but Conveniency: Therefore saith Mark, when a Convenient day was come, when probably Herod should be over merry with Wine, or should be busie with his Company, and not so much at leisure to consider what he did: It so happened that the Daughter of this Herodias Danced before Herod upon his Birth-day. The keeping of Birth-days was usual amongst the Eastern Kings, Pharaoh kept his Birth-day, Gen. 40.20. Some by it understand the day of the Princes Coronation, or Entrance upon his Government, which some think is meant, Hos. 7.5. by the day of the King, when the Princes made him sick with Bottles of Wine. The Iews reckoned them both amongst the Pagan Festivals, but they had both derived this, and many other usages from them. Dancing was much used amongst them at their Festivals. It seemeth this Daughter of Herodias pleased Herod more than ordinary: He sweareth that he would give her what she would ask, to the half of his Kingdom. That Phrase by Esther 5.3. seemeth to have been ordinary with Princes, when they made liberal Promises.
