Michal was the daughter of King Saul and David's wife. When her father wanted to kill David, Michal warned him, and he escaped. She pretended that he was sick in bed. While he was gone, Saul gave Michal to Palti to marry, and in the meantime, David took several other wives. Although Deuteronomy 24 makes it clear that is against the Law for a man to remarry a wife once he has divorced her and she had been defiled by another husband, David had not divorced her, and so he demanded her return once he became king.
