Valley running north-south on the east side of Jerusalem, between the city walls and the Mount of Olives. The Brook Kidron flows through it during the rainy season; it serves as the principal boundary between Jerusalem proper and the Mount of Olives, leading down toward the Dead Sea. Several major biblical narratives cross the Kidron Valley. (1) David fleeing Absalom: And all the country wept with a loud voice, and all the people passed over: the king also himself passed over the brook Kidron (2 Samuel 15:23); the typological echo with Christ's later crossing the same brook on the night of His betrayal is significant. (2) The reformer-kings of Judah (Asa, Hezekiah, Josiah) brought their idolatrous abominations down to the Kidron Valley to be destroyed and burned (1 Kings 15:13; 2 Kings 23:4, 6, 12; 2 Chronicles 15:16; 29:16; 30:14) — Kidron becoming the place where Judah's idolatries were physically removed. (3) On the night of His betrayal, Christ went forth with his disciples over the brook Cedron [Kidron], where was a garden, into the which he entered, and his disciples (John 18:1) — the Garden of Gethsemane lay just across the Kidron at the foot of the Mount of Olives. The Lord Jesus's deliberate crossing of the Kidron on the way to His arrest is theologically rich: David crossed the Kidron in flight from Absalom's treachery; the greater Son of David crossed the Kidron toward the treachery of Judas. Joel 3:2 and 3:12 prophesy the LORD's eschatological judgment in the valley of Jehoshaphat, traditionally identified with the Kidron. The patriarchal-Reformed reader receives Kidron as the boundary-valley between the holy city and the Mount of Olives, the place of removal of idolatries by the reformer-kings, and the path of Christ to Gethsemane.
