Hezekiah stopped the upper watercourse of Gihon A rivulet near Jerusalem, consisting of two streams, the upper, which was brought into one pool, called the upper pool, (Isaiah 7:3,) and the lower, which was brought into another, called the lower pool, Isaiah 22:9. The former he diverted, and brought by pipes into Jerusalem, which was a work of great art and labour. And brought it straight down to the city of David Whereas before it fetched a compass, and therefore might have been beneficial to the Assyrian host.
