29:12-40 Soon after the day of atonement, the day in which men were to afflict their souls, followed the feast of Tabernacles, in which they were to rejoice before the Lord. Their days of rejoicing were to be days of sacrifices. A disposition to be cheerful does us good, when it encourages our hearts in the duties of God's service. All the days of dwelling in booths they must offer sacrifices; while we are here in a tabernacle state, it is our interest, as well as our duty, constantly to keep up communion with God. The sacrifices for each of the seven days are appointed. Every day there must be a sin-offering, as in the other feasts. Our burnt-offerings of praise cannot be accepted of God, unless we have an interest in the great sacrifice which Christ offered, when he made himself a Sin-offering for us. And no extraordinary services should put aside stated devotions. Every thing here reminds us of our sinfulness. The life that we live in the flesh must be by the faith of the Son of God; until we go to be with him, to behold his glory, and praise his mercy, who hath loved us and washed us from our sins in his own blood. To whom be honour and glory for ever. Amen.

35-40. On the eighth day ye shall have a solemn assembly—The feast of tabernacles was brought to a close on the eighth day, which was the great day (Joh 7:37). Besides the common routine sacrifices, there were special offerings appointed for that day though these were fewer than on any of the preceding days; and there were also, as was natural on that occasion when vast multitudes were convened for a solemn religious purpose, many spontaneous gifts and services, so that there was full scope for the exercise of a devout spirit in the people, both for their obedience to the statutory offerings, and by the presentation of those which were made by free will or in consequence of vows.
