‘ And one of the sons of Ahimelech, the son of Ahitub, named Abiathar, escaped, and fled after David.'
One of the sons of Ahimelech, however, somehow escaped and ‘fled after David'. His name was Abiathar. He was becoming a refugee like David, and would later become David's High Priest, before losing his status in the time of Solomon when he took part in the rebellion of Adonijah.
