Despising Heart

1 Chronicles 15:29
As the ark of the covenant of the LORD was entering the City of David, Michal daughter of Saul watched from a window. And when she saw King David dancing and celebrating, she despised him in her heart.

We're going back in time to David. This verse is the same as 2 Samuel 6:16, and I wrote on it then. I paraphrased it then in terms of Michal's secret thoughts, but I think you could also consider the heart here as the seat of the affections, passions, and emotions, as distinguished from the intellect and will. She let her emotions rule, and she took the opportunity to speak bitterly and contemptuously to her husband and king.
Her angry rebuke is not brought up in Chronicles, nor David's reply. Instead, from this quick POV switch, we go right back to the worship-party, where David the priest-king makes sacrifices, gives food to all, and gives the worship band his new song. Indeed, the next chapter ends with his blessing his family, and the next one goes on to tell of his inspiration to build a temple. Think of it, the return of the ark was to the tabernacle.
But in the midst of all this worship and joy--one bitter heart.
