John Wesley on 1 Samuel 22:10

He enquired - David chargeth him with the sin of lying, Psal 52:3, and it is not improbable, that he told many lies not here expressed; and withal, he was guilty of concealing part of the truth, which in this case he was obliged to declare for Ahimelech's just defence, namely, the artifice whereby David circumvented Ahimelech: making him believe, that he was then going upon the king's business, so that the service he did to David, was designed in honour to Saul.
