Matthew Henry on 1 Samuel 23:19-29

In the midst of his wickedness, Saul affected to speak the language of piety. Such expressions, without suitable effects, can only amuse or deceive those who hear, and those who use them. This mountain was an emblem of the Divine Providence coming between David and the destroyer. Let us not be dismayed at the prospect of future difficulties, but stay ourselves upon Him who is wonderful in counsel and excellent in working. Sooner than his promise shall fail, he will commission Philistines to effect our escape, at the very moment when our case appears most desperate. God requires entire dependence on him, If ye will not believe, surely ye shall not be established, Isa 7:9.
