Adam Clarke on 2 Samuel 6:22

I will yet be more vile - The plain meaning of these words appears to be this: "I am not ashamed of humbling myself before that God who rejected thy father because of his obstinacy and pride, and chose me in his stead to rule his people; and even those maid-servants, when they come to know the motive of my conduct, shall acknowledge its propriety, and treat me with additional respect; and as for thee, thou shalt find that thy conduct is as little pleasing to God as it is to me." Then it is said, Michal had no child till the day of her death: probably David never more took her to his bed; or God, in his providence, might have subjected her to barrenness which in Palestine was considered both a misfortune and a reproach. Michal formed her judgment without reason, and meddled with that which she did not understand. We should be careful how we attribute actions, the reasons of which we cannot comprehend, to motives which may appear to us unjustifiable or absurd. Rash judgments are doubly pernicious; they hurt those who form them, and those of whom they are formed.
