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.

And I will yet be more vile than thus,.... If this is to be vile, I will endeavour to be viler still; if to dance before the ark, and sing the praises of God, be reckoned a lessening of me, I will more and more be found in doing such things, or what is similar to them:
and will be base in mine own sight: humble himself, and lie low in his own eyes, admiring the grace and goodness of God to him, thinking he could never condescend too low to exalt the Lord, and magnify the riches of his goodness:
and of the maidservants which thou hast spoken of, of them shall I be had in honour; who the more humble I am, and the more I condescend, by laying aside all state in acts of devotion and religion, the more shall I be honoured and spoken well of by them.

More vile than thus - The more we are vilified for well doing, the more resolute therein we should be, binding our religion the closer to us, for the endeavours of Satan's agents to shame us out of it. Be base - I will always be ready to abase myself before God, and think nothing to mean to stoop to for his honour. Be had in honour - So far will they be from despising me on this account, that they will honour me the more.
