The ancient road from Jerusalem to Jericho is a narrow, treacherous path along a deep gorge in the Judean wilderness. Its name is Wadi Kelt, but it’s known as the valley of the shadow, for this is the location that inspired David’s 23rd Psalm. The place itself offers little reason to compose such a hopeful poem. The landscape is bleak, barren, and perilously steep. It’s a good place for thieves, but not for anyone else.
