Herod does not want to break his word (Mk 6:26-6:26)

“The king

Was deeply grieved.

Yet out of regard

For his oaths

And his guests.

He did not want

To refuse her.”

 

καὶ περίλυπος γενόμενος ὁ βασιλεὺς διὰ τοὺς ὅρκους καὶ τοὺς ἀνακειμένους οὐκ ἠθέλησεν ἀθετῆσαι αὐτήν.

 

This is similar to Matthew, chapter 14:9.  Mark said that King Herod had become pained and sorry (καὶ περίλυπος γενόμενος ὁ βασιλεὺς) for what he had just promised, much like in the story of Esther, chapter 5:3, where the king was willing to give Esther anything she wanted.  Yet out of regard for his oaths (διὰ τοὺς ὅρκους) and his guests reclining at table with him (καὶ τοὺς ἀνακειμένους), he would not refuse her (οὐκ ἠθέλησεν ἀθετῆσαι αὐτήν).  Watch what you say on the spur of the moment.
