1 Samuel 29:10

With thy master's servants; he intimates the ground of the Philistines jealousy concerning David and his men, that they were all servants of Saul, and therefore had an obligation, and were suspected to have an affection, to their old lord and master, against whom even David himself could not make them fight, especially with and for the Philistines. As soon as ye have light, depart; before the battle begin, lest, if you delay, the lords of the Philistines fall upon you, and destroy you.
