14 They found written in the law, how that Yahweh had commanded by Moses, that the children of Israel should dwell in booths in the feast of the seventh month; 15 and that they should publish and proclaim in all their cities, and in Jerusalem, saying, Go forth to the mountain, and get olive branches, and branches of wild olive, and myrtle branches, and palm branches, and branches of thick trees, to make booths, as it is written. 16 So the people went forth, and brought them, and made themselves booths, everyone on the roof of his house, and in their courts, and in the courts of the house of God, and in the broad place of the water gate, and in the broad place of the gate of Ephraim. 17 All the assembly of those who were come again out of the captivity made booths, and lived in the booths; for since the days of Jeshua the son of Nun to that day the children of Israel had not done so. There was very great gladness. 18 Also day by day, from the first day to the last day, he read in the book of the law of God. They kept the feast seven days; and on the eighth day was a solemn assembly, according to the ordinance.

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.
