The sons of the prophets - The expression occurs here for the first time. It signifies (marginal references), the schools or colleges of prophets which existed in several of the Israelite, and probably of the Jewish, towns, where young men were regularly educated for the prophetical office. These “schools” make their first appearance under Samuel 1 Samuel 19:20. There is no distinct evidence that they continued later than the time of Elisha; but it is on the whole most probable that the institution survived the captivity, and that the bulk of the “prophets,” whose works have come down to us belonged to them. Amos Amos 7:14-15 seems to speak as if his were an exceptional case.
Said unto his neighbor - Rather, “to his friend” or “companion “ - to one who was, like himself, “a prophet’s son,” and who ought therefore to have perceived that his colleague spoke “in the word of the Lord.”
