Bede

But Saul recognized David's voice, etc. Saul, recognizing David's voice, moved by his humility, innocence, and justice, confessed that he had sinned and promised not to sin against him anymore, and orders him to return. Many of the leaders of the Jews, recognizing the voice of Christ through the apostles' exhortation, confessed that they had sinned, repenting, and implored him with many tears and great prayers to return by the grace of forgiveness to their hearts, which he had deserted because of their faithlessness.
