1 Samuel 19:18

David...came to Samuel. We have seen that there is every reason to believe that David had been taught and trained by Samuel among the sons of the prophets, and now, conscious of his innocence, he flees for refuge to his old master, trusting that Saul would reverence God's prophet, and give credence to his intercession and his pledge that David was guiltless. He and Samuel went and dwelt in Naioth. Rather in Nevayoth, as in the written text. This is not the name of a place, but signifies "dwellings," "lodgings," and is always translated in the Chaldee "house of study," i.e. student's lodgings. Somewhere near to Ramah Samuel had erected buildings to receive his young men, who were called "sons of the prophets," not because their fathers were prophets, but because they were under prophetic training, with prophets for their teachers, though not necessarily intended to be prophets themselves. At first Samuel, we may suppose, built one nevath, one simple hospice for his students, and then, as their numbers grew, another, and yet another, and so the plural, nevayoth, came into voile as the name of the students' quarters.
