Herod, on his birthday, gave a banquet for his courtiers, his military officers, and the leading men of Galilee. Herodias’s own daughter (named Salome in Josephus) came in and performed a dance that delighted Herod and his guests. The king said to the girl, “Ask of me whatever you wish and I will grant it to you.” He even swore [many things] to her, “I will grant you whatever you ask of me, even to half of my kingdom.”
Modern depictions of this event often play up its sexual connotations, portraying Herod Antipas as a lecherous old man salivating as his step daughter performed something called the Dance of the Seven Veils. It turns out this dance is a fiction, and the text says only that it delighted Herod and his guests - so much so that he offered half his kingdom as a reward.
My question is what motivated him? Was it lechery? Should we give him the benefit of the doubt and see his offer as the result of his heart being moved by Salome's innocent dance of modest maidenly beauty? Or was it perhaps the fact that his marriage to Herodias was a subject of public controversy and by making such an offer to Salome in a public setting, Antipas was demonstrating a commitment to accept Herodias' offspring as his own, despite not being her physical father?
NOTE: Interpretations from various denominational perspectives are welcome. I ask the question here rather than BH.se because the text itself provides no direct answer.
