29:1-19 When Hezekiah came to the crown, he applied at once to work reform. Those who begin with God, begin at the right end of their work, and it will prosper accordingly. Those that turn their backs upon God's ordinances, may truly be said to forsake God himself. There are still such neglects, if the word be not duly read and opened, for that was signified by the lighting the lamps, and also if prayers and praise be not offered up, for that was signified by the burning incense. Neglect of God's worship was the cause of the calamities they had lain under. The Lord alone can prepare the heart of man for vital godliness: when much good is done in a little time, the glory must be ascribed to him; and all who love him or the souls of men, will rejoice therein. Let those that do good work, learn to do it well.

They "shut up the doors of the porch," so that the sacred ritual was entirely discontinued.
