John Wesley on 1 Samuel 29:3

The princes - The Lords of the other eminent cities, who were confederate with him in this expedition. These days or years - That is, did I say days? I might have said years. He hath now been with me a full year and four months, chap.27:7, and he was with me some years ago, 1Sam 21:10, and since their time hath been known to me. And it is not improbable, but David, after his escape from thence, might hold some correspondence with Achish, as finding him to be a man of a more generous temper than the rest of the Philistines, and supposing that he might have need of him for a refuge, in case Saul continued to seek his life. Since he fell - Revolted, or left his own king to turn to me.
