Michal, the daughter of Saul, is a portrait of unrequited love, which is how the artist interprets Michal's bitter reaction to David's homecoming to Jerusalem a victor in Israel's wars.
2 Samuel 6:14-23
David, wearing a linen ephod, danced before God with all his might, while he and the entire house of Israel brought up the ark of God with shouts and the sound of trumpets.
As the ark of God was entering the City of David, Michal daughter of Saul watched from a window. And when she saw King David leaping and dancing before God, she despised him in her heart.
They brought the ark of God and set it in its place inside the tent that David had pitched for it, and David sacrificed burnt offerings and fellowship offerings before God. After he had finished sacrificing the burnt offerings and fellowship offerings, he blessed the people in the name of God Almighty. Then he gave a loaf of bread, a cake of dates and a cake of raisins to each person in the whole crowd of Israelites, both men and women. And all the people went to their homes.
When David returned home to bless his household, Michal daughter of Saul came out to meet him and said, "How the king of Israel has distinguished himself today, disrobing in the sight of the slave girls of his servants as any vulgar fellow would!"
David said to Michal, "It was before God, who chose me rather than your father or anyone from his house when he appointed me ruler over God people Israel—I will celebrate before God. I will become even more undignified than this, and I will be humiliated in my own eyes. But by these slave girls you spoke of, I will be held in honor."
And Michal daughter of Saul had no children to the day of her death.
