Albert Barnes Commentary 1 Samuel 19:18

"Now David fled, and escaped, and came to Samuel to Ramah, and told him all that Saul had done to him. And he and Samuel went and dwelt in Naioth." — 1 Samuel 19:18 (ASV)

No such place as Naioth (or Nevaioth) is known, but the word means “dwellings.” Therefore, it is considered that Naioth was the name of the collegiate residence of the prophets, in or just outside Ramah, to which Samuel moved with David from his own house for greater safety, because of the sanctity of the place and the company.
