you’re right in that her resoning was that she felt it was unbecoming. but WHAT did she feel was unbecoming? what was she sensetive to? the fact that his leg showed. it was the tznius that she learnt from her father. true, (whether right or wrong) shaul might have not been the type to dance in public at all. but michal wasn’t rebuking david for dancing. she wasn’t stupid – she knew her father and david were very different and had differnt ways of serving hashem and she accepted that. except for when it touched on shaul’s greatness. and like i said, she was wrong and she was punished for it. but WHERE was that coming from? a praiseworthy aspect of king shaul.
