Day 4. Old Testament walk this morning. Walked c. 1/3 mile in the tunnel Hezekiah built to bring water inside Jerusalem’s wall. Saw the excavated ruins of David’s palace and an original corner of Nehemiah’s wall. Attended a lecture this afternoon. Went to the west wall of the Temple Mount this evening and then went underground to look at more of the west Temple Mount wall that is not visible at ground level. Walked 6 1/2 miles today. Tomorrow we will focus on a New Testament Jerusalem walk.
