Saul went home - Confounded at a sense of his own baseness, and overwhelmed with a sense of David's generosity.
David and his men gat them up unto the hold - Went up to Mizpeh, according to the Syriac and Arabic. David could not trust Saul with his life; the utmost he could expect from him was that he should cease from persecuting him; but even this was too much to expect from a man of such a character as Saul. He was no longer under the Divine guidance; an evil spirit had full dominion over his soul. What God fills not, the devil will occupy.
Saul does not appear to have invited David to return to Gibeah, or to have given him any security of doing so with safety. David, with his intuitive sagacity, perceived that the softening of Saul‘s feelings was only momentary, and that the situation remained unchanged.
