Robert Alter on 1 Samuel 26:22

 

And David answered and said, “Here is the king’s spear.” It is noteworthy that David does not immediately respond to Saul’s renewed profession of regret and good faith. (The Masoretic consonantal text, the ketiv, tries to rescue this lapse by representing these words as a vocative, “Here is the spear, king,” but the qeri, or pronounced Masoretic version, properly renders it as ḥanit hamelekh, “the king’s spear.”) In the encounter at the cave, David vowed he would not harm Saul’s descendants, though his actual words were not reported. Here, he first gives an impersonal order to have the spear brought back to Saul. It is only when he goes on to recapitulate his profession of innocence that he again addresses Saul. By this point, he no longer trusts any promises Saul may make not to harm him but hopes that God will note his own proper conduct and therefore protect him (verse 24).
