They repaired the wall and gathered the water (22:9-11). Was that wrong?

The chapter doesn't say the work itself was wrong or right. It tells what was done: "you gathered together the waters of the lower pool" (22:9), "you broke down the houses to fortify the wall" (22:10), "You also made a reservoir between the two walls" (22:11). Then it says, "But you didn’t look to him who had done this, neither did you have respect for him who planned it long ago" (22:11). The but sets what they did beside what they didn't do. The next verses name something else: the Lord "called to weeping, to mourning" (22:12), "and behold, there is joy and gladness" (22:13). The chapter's charge is in these verses, and it says nothing more about the wall or the pool. The book has words like 22:11's in other chapters. "In that day, people will look to their Maker, and their eyes will have respect for the Holy One of Israel" (Isaiah 17:7), where Maker is the Hebrew word of 22:11's him who had done this; and "Woe to those who go down to Egypt for help, and rely on horses" (Isaiah 31:1), "but they don’t look to the Holy One of Israel, and they don’t seek the LORD!" (Isaiah 31:1). These notes set the verses side by side and say no more.
