Stress is laid on the number seven, the holy symbolic covenant number, by way of intimation that the mercies of the harvest accrued by virtue of God's covenant. The diminishing number of bullocks sacrificed on the preceding days of the Feast (compare Numbers 29:13, Numbers 29:17, etc.), is adjusted simply to obtain the coincidence before us on the seventh day; but some have thought that the gradual evanescence of the Law until the time of its absorption in the Gospel is here presignified in the Law itself.

And on the seventh day seven bullocks, two rams, and fourteen lambs of the first year without blemish:

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.
