1 Samuel 29

3. these days, or these years--He had now been with the Philistines a full year and four months ( 1 Samuel 27:7 ), and also some years before. It has been thought that David kept up a private correspondence with this Philistine prince, either on account of his native generosity, or in the anticipation that an asylum in his territories would sooner or later be needed.

4. the princes of the Philistines were wroth with him--It must be considered a happy circumstance in the overruling providence of God to rescue David out of the dangerous dilemma in which he was now placed. But David is not free from censure in his professions to Achish ( 1 Samuel 29:8 ), to do what he probably had not the smallest purpose of doing--of fighting with Achish against his enemies. It is just an instance of the unhappy consequences into which a false step--a departure from the straight course of duty--will betray everyone who commits it.

9. notwithstanding the princes of the Philistines have said--The Philistine government had constitutional checks--or at least the king was not an absolute sovereign; but his authority was limited--his proceedings liable to be controlled by "the powerful barons of that rude and early period--much as the kings of Europe in the Middle Ages were by the proud and lawless aristocracy which surrounded them" [CHALMERS].
