Mark 6:26

Καὶ περίλυπος γενόμενος ὁ βασιλεύς, διὰ τοὺς ὅρκους καὶ τοὺς συνανακειμένους οὐκ ἠθέλησεν αὐτὴν ἀθετῆσαι.

RBT Translation:

ἀθετῆσαι - Set Aside, Violate, Invalidate

And he who has become grieved all around, the King did not want to invalidate herself because of the Oaths and the ones who are dedicated.

Julia Smith Literal 1876 Translation:
And the king having been sorely grieved on account of the oaths and those reclining at table together, wished not to refuse her.

LITV Translation:
And becoming deeply grieved, but because of the oaths and those reclining together, the king did not wish to reject her.
