We have here,

I.The people's renewed attendance upon the word. They had spent the greatest part of one day in praying and hearing, and yet were so far from being weary of that new moon and sabbath that the next day after, though it was no festival, the chief of them came together again to hear Ezra expound (Neh 8:13), which they found more delightful and gainful than any worldly pleasure or profit whatsoever. Note, The more we converse with the word of God, if we rightly understand it and be affected with it, the more we shall covet to converse with it, and to increase in our acquaintance with it, saying, How sweet are thy words unto my mouth! Those that understand the scriptures well will still be desirous to understand them better. Now the priests and the Levites themselves came with the chief of the people to Ezra, that prince of expositors, to understand the words of the law, or, as it is in the margin, that they might instruct in the words of the law; they came to be taught themselves, that they might be qualified to teach others. Observe, 1. Though, on the first day, Ezra's humility had set them on his right hand and on his left, as teachers with him (Neh 8:4, Neh 8:7), yet now, they being by trial made more sensible than ever of their own deficiencies and his excellencies, on the second day their humility set them at Ezra's feet, as learners of him. 2. Those that would teach others must themselves receive instructions. Priests and Levites must be taught first and then teach.

II.The people's ready obedience to the word, in one particular instance, as soon as they were made sensible of their duty therein. It is probable that Ezra, after the wisdom of his God that was in his hand (Ezr 7:25), when they applied to him for instruction out of the law on the second day of the seventh month, read to them those laws which concerned the feasts of that month, and, among the rest, that of the feast of tabernacles, Lev 23:34; Deu 16:13. Ministers should preach not only that which is true and good, but that which is seasonable, directing to the work of the day in its day. Here is, 1. The divine appointment of the feast of tabernacles reviewed, Neh 8:14, Neh 8:15. They found written in the law a commandment concerning it. Those that diligently search the scriptures will find those things written there which they had forgotten or not duly considered. This feast of tabernacles was a memorial of their dwelling in tents in the wilderness, a representation of our 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 (Zac 14:16); they shall come to keep the feast of tabernacles, as having here no continuing city. This feast was to be proclaimed in all their cities. The people were themselves to fetch boughs of trees (they of Jerusalem fetched them from the mount of Olives) and to make booths, or arbours, of them, in which they were to lodge (as much as the weather would permit) and to make merry during the feast. 2. This appointment religiously observed, Neh 8:16, Neh 8:17. Then 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. (1.) They observed the ceremony: They sat in booths, which the priests and Levites set up in the courts of the temple; those that had houses of their own set up booths on the roofs of them, or in their courts; and those that had not such conveniences set them up in the streets. This feast had usually been observed (Ch2 5:3; Ezr 3:4), but never with such solemnity as now since Joshua's time, when they were newly settled, as they were now newly re-settled in Canaan. That man loves his house too well that cannot find in his heart to quit it, awhile, in compliance either with an ordinance or with a providence of God. (2.) They minded the substance, else the ceremony, how significant soever, would have been insignificant. [1.] They did it with gladness, with very great gladness, rejoicing in God and his goodness to them. All their holy feasts, but this especially, were to be celebrated with joy, which would be much for the honour of God, and their own encouragement in his service. [2.] They attended the reading and expounding of the word of God during all the days of the feast, v. 18. They improved their leisure for this good work. Spare hours cannot be better spent than in studying the scriptures and conversing with them. At this feast of tabernacles God appointed the law to be read once in seven years. Whether this was that year of release in which that service was to be performed (Deu 31:10, Deu 31:11) does not appear; however they spent all the days of the feast in that good work, and on the eighth day was a solemn assembly, as God had appointed, in which they finished the solemnity the twenty-second day of the month, yet did not separate, for the twenty-fourth day was appointed to be spent in fasting and prayer. Holy joy just not indispose us for godly sorrow any more than godly sorrow for holy joy.

In the feast of the seventh month - That is, the feast of tabernacles, which was held in commemoration of the sojourning of their fathers in the wilderness after they had been delivered from the Egyptian bondage. Now, having been delivered from the Babylonish captivity, and the proper time of the year occurring, it was their especial duty to keep the same feast.

And they found written in the law which the Lord had commanded by Moses,.... The children of Israel, to be observed by them; either by hearing it read the day before, or by conversation with Ezra, they perceived it was enjoined in the law, particularly in Lev 23:39

that the children of Israel should dwell in booths, in the feast of the seventh month: which was the same month, and this the second day of it, and therefore the time drew near for keeping it; for it was to begin the fifteenth.

THE PEOPLE COMFORTED. (Neh 8:9-15)

This day is holy unto the Lord . . . mourn not, nor weep--A deep sense of their national sins, impressively brought to their remembrance by the reading of the law and its denunciations, affected the hearts of the people with penitential sorrow. But notwithstanding the painful remembrances of their national sins which the reading of the law awakened, the people were exhorted to cherish the feelings of joy and thankfulness associated with a sacred festival (see on Lev 23:24). By sending portions of it to their poorer brethren (Deu 16:11, Deu 16:14; Est 9:19), they would also enable them to participate in the public rejoicings.
