Contemptuous Heart

2 Samuel 6:16
As the ark of the LORD was entering the City of David, Michal daughter of Saul watched from a window. And when she saw King David leaping and dancing before the LORD, she despised him in her heart.

Michal was part of Abner's story in chapter 3. Saul had taken her away from David, so David demanded that Abner arrange her return, though she'd been married to another.
The opening lines of chapter 6 show that he didn't exactly need her; he had at least 6 wives already, bearing him sons. It seems like a power play, a simple demand for everything to be restored to him, not only all of Israel, but one woman who had once been his.
This is the story of the ark as well, that had languished at Kiriath Jearim for years because everyone was afraid to touch it. David, with his love for true worship, wanted the ark back in Jerusalem. His first attempt was badly-planned, and two men died before it was stranded once more at the house of Obed-Edom the Gittite.
Now he's done his research, and somebody remembered that the ark has to be carried on its poles, never loaded on a cart. The carrying is done with huge celebration--sacrifices, shouting, trumpets. . .and dancing.
Maybe Michal was already mad at him. Hard to see how she could be happy when she's been a pawn for kings most of her adult life. But the dancing was the last straw. Deep inside, in her secret thoughts, she hated David, whom she'd once loved.
David had no need to apologize, and from the last line of the chapter, it looks as if their marriage was thereby over.
God, help me to never judge another's worship. Keep my heart free from hate.
