The offerings prescribed for the closing day of the Feast of tabernacles were the same with those appointed for the Feast of Trumpets and the Day of Atonement. The solemnities of the month thus terminated, as
A whole, with the same sacrifices with which, three weeks before, they had been introduced; and the Day of Atonement, even though succeeded by the rejoicings of the Feast of tabernacles, thus left its impress on the whole month.

On the eighth day ye shall have a solemn assembly - This among the Jews was esteemed the chief or high day of the feast, though fewer sacrifices were offered on it than on the others; the people seem to have finished the solemnity with a greater measure of spiritual devotion, and it was on this day of the feast that our blessed Lord called the Jews from the letter to the spirit of the law, proposing himself as the sole fountain whence they could derive the streams of salvation, John 7:37. On the subject of this chapter see the notes on Leviticus 12:1-8 (note), Leviticus 16 (note), Leviticus 23 (note).

On the eighth day ye shall have a solemn assembly,.... The day after the seven days of the feast of tabernacles were ended; for this was not properly a part of that feast, but was a sort of appendage to it:
ye shall do no servile work therein; See Gill on Leviticus 23:36.

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 (John 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.

The eighth day was to be azereth, a closing feast, and only belonged to the feast of Tabernacles so far as the Sabbath rest and a holy meeting of the seventh feast-day were transferred to it; whilst, so far as its sacrifices were concerned, it resembled the seventh new moon's day and the day of atonement, and was thus shown to be the octave or close of the second festal circle (see at Leviticus 23:36).
