For he said to Judah, "Let us build these cities, and make walls around them, with towers, gates, and bars. The land is yet before us, because we have sought the LORD our God; we have sought him, and he has given us rest on every side." So they built and prospered.

In every work that he began in the service of God's house, and in the law, and in the commandments, to seek his God, he did it with all his heart, and prospered.

This same Hezekiah also stopped the upper spring of the waters of Gihon, and brought them straight down on the west side of the City of David. Hezekiah prospered in all his works.
