2 Samuel 6:12-16

Now King David was told, “The LORD has blessed the house of Obed-edom and all that belongs to him, because of the ark of God.” So David went and brought up the ark of God from the house of Obed-edom into the City of David with rejoicing and gladness. And when those who were carrying the ark of the LORD [by its poles] had gone six paces, he sacrificed an ox and a fatling. And David was dancing before the LORD with great enthusiasm, and David was wearing a linen ephod [a priest’s upper garment]. So David and all the house of Israel were bringing the ark of the LORD up [to the City of David] with shouts [of joy] and with the sound of the trumpet. Then, as the ark of the LORD came into the City of David, Michal, Saul’s daughter [David’s wife], looked down from the window above and saw King David leaping and dancing before the LORD; and she felt contempt for him in her heart [because she thought him undignified].
