11 and you constructed a basin between the two walls for the water of the old pool. But you gave no thought to Him who planned it, You took no note of Him who designed it long before.

22:11 And you constructed a basin between the two walls
Verses 8-11 describe the serious military preparations made to fend off the upcoming Assyrian assault. Yeshayahu does not oppose this per se — he simply asks that they combine their trust in themselves with faith in Hashem. The “basin between the two walls” refers to Chizkiyahu’s tunnel, which he dug in order to provide a source of water for the besieged city of Yerushalayim (II Chronicles 32). The tunnel was re-discovered in 1867 by the British explorer Captain Charles Warren. Near the exit from the tunnel, an ancient Hebrew inscription describing its amazing construction was discovered. A team of diggers started at each end of the 1,500 foot-long tunnel. They eventually met in the middle by listening for the sounds of each other’s pickaxes. The marks of the ancient pickaxes are visible on the walls of the tunnel, going first in one direction and switching in the middle to go in the other direction. Today, wading through the water of Chizkiyahu’s tunnel is a popular attraction among visitors to the city of Yerushalayim.
