As the title, in Book 2 of Shmuel Chapter 6 it says that Michal peered through her window and saw King David dancing and loathed him for doing so: "And David danced with all his might before the Lord; and David was girded with a linen ephod. ידוְדָוִד מְכַרְכֵּר בְּכָל עֹז לִפְנֵי יְהֹוָה וְדָוִד חָגוּר אֵפוֹד בָּד: 15And David and all the house of Israel brought up the ark of the Lord with shouting and with the sound of [the] shofar. טווְדָוִד וְכָל בֵּית יִשְׂרָאֵל מַעֲלִים אֶת אֲרוֹן יְהֹוָה בִּתְרוּעָה וּבְקוֹל שׁוֹפָר: 16And [as] the ark of the Lord came [into] the city of David, Michal the daughter of Saul peered through the window, and she saw the king David hopping and dancing before the Lord; and she loathed him in her heart." and she goes on to greet him later and rebuke him for doing so and then tells him ""How honored was today the king of Israel, who exposed himself today in the eyes of the handmaids of his servants, as would expose himself one of the idlers."
Did King David Expose himself (nude) while dancing or was it just unfit for him in the eyes of Michal?
