1 Samuel 20:1

While Saul was under the constraining influence of the spirit of prophecy, David escaped from Naioth, and, probably by Samuel’s advice, returned to Saul’s court to commune with Jonathan. Nothing could be a better evidence of his innocence than thus putting himself in Jonathan’s power. Perhaps something passed between Samuel and Saul on the subject, since it appears from 1Sa 20:5, 1 Samuel 20:25, 1 Samuel 20:27, that Saul expected David at the feast of the new moon.
