16 So the people went out, brought in branches, and made themselves booths on their roofs, courtyards, the courtyards of The Temple of God, the Water Gate plaza, and the Ephraim Gate plaza. 17 The entire congregation that had come back from exile made booths and lived in them. The People of Israel hadn't done this from the time of Joshua son of Nun until that very day - a terrific day! Great joy! 18 Ezra read from the Book of The Revelation of God each day, from the first to the last day - they celebrated the feast for seven days. On the eighth day they held a solemn assembly in accordance with the decree.

(Read Nehemiah 8:13-18)
They found written in the law about the feast of tabernacles. Those who diligently search the Scriptures, find things written there which they have forgotten. This feast of tabernacles was a representation of the believer's tabernacle state in this world, and a type of the holy joy of the gospel church. The conversion of the nations to the faith of Christ, is foretold under the figure of this feast, Zechariah 14:16. True religion will render us strangers and pilgrims upon earth. We read and hear the word acceptably and profitably, when we do according to what is written therein; when what appears to be our duty is revived, after it has been neglected. They minded the substance; else the ceremony had been of no use. They did it, rejoicing in God and his goodness. These are the means which the Spirit of God crowns with success, in bringing the hearts of sinners to tremble and to become humbled before God. But those are enemies to their own growth in holiness, who always indulge sorrow, even for sin, and put away from them the consolations tendered by the word and Spirit of God.
