There was a considerable drop-off in the south and eastern corner of the city. From the Fountain Gate a set of stairs evidently led away from the city, perhaps going past the pools. Shallum’s responsibility extended as far as (the top of) these stairs.
15 And Shallum the son of Col-hozeh, ruler of the district of Mizpah, repaired the Fountain Gate. He rebuilt it and covered it and set its doors, its bolts, and its bars. And he built the wall of the Pool of Shelah of the king’s garden, as far as the stairs that go down from the city of David.
