Albert Barnes Commentary 2 Kings 2:3

"And the sons of the prophets that were at Beth-el came forth to Elisha, and said unto him, Knowest thou that Jehovah will take away thy master from thy head to-day? And he said, Yea, I know it; hold ye your peace." — 2 Kings 2:3 (ASV)

Came forth to Elisha - It does not appear that any conversation took place between the “sons of the prophets” and Elijah. However, independent revelations had been made to the two “schools” at Bethel and Jericho (2 Kings 2:5), and also to Elisha, regarding Elijah’s impending removal.

From thy head - That is, from his position as teacher and master. The teacher sat on an elevated seat, so that his feet were level with the heads of his pupils .

Hold ye your peace - That is, “Say nothing—do not disturb us. The matter is too sacred for words.”
