Matthew Henry on 1 Samuel 21:10–end
David, though king elect, is here an exile - designed to be master of vast treasures, yet just now begging his bread - anointed to the crown, and yet here forced to flee from his country. Thus do God's providences sometimes seem to run counter to his promises, for the trial of his people's faith, and the glorifying of his name, in the accomplishment of his counsels, notwithstanding the difficulties that lay in the way. Here is, 1. David's flight into the land of the Philistines, where he hoped to be hid, and to remain undiscovered in the court or camp of Achish king of Gath, Sa1 21:10.

And what so likely to deceive as the very reverse of that character which they had so misconstrued? He was undone as a wise man, he had a chance to escape as a madman; he tried, and the experiment succeeded." I confess I can neither feel the force nor the morality of this. Deceit and hypocrisy can never be pleasing in the sight of God.
John Gill on 1 Samuel 21:15
Have I need of madmen?.... Or fools, do I want them? have not I enough of them already at my court? I want wise men, and not fools and madmen. The Jews say (w) that the wife and daughter of Achish were mad; that while David was playing the fool and madman without, they were acting the same part within; so that Achish had enough of that sort of diversion, if it was to be reckoned such; as it was according to the taste of some persons, who used, as in later so in earlier times, to keep fools in their houses to make them sport; but Achish had enough of that, and too much, at least needed no more:
that ye have brought this fellow to play the madman in my presence? or act the part of a fool befo…
