En-rogel is a spring (natural water source) near Jerusalem. En-rogel marked part of the border between the tribes of Judah and Benjamin (Joshua 15:7; 18:16).
Jonathan and Ahimaaz once hid at En-rogel while spying on Absalom’s army for King David (2 Samuel 17:17). A servant girl carried their message from the spring to the king. Later, Adonijah offered sacrifices there when he tried to make himself king before David died (1 Kings 1:9).
Some think En-rogel was a spring in a cave near Siloam, on the west side of the Kidron Valley. This spring is called the Virgin’s Fount. However, many scholars believe this spring is actually the Gihon Spring (1 Kings 1:33), which the Bible treats as a different place. A better suggestion is that En-rogel was a spring south of Jerusalem, known today as the Well of Job.
