Numbers 29

⁶Beside the burnt offering of the month, and his meat offering, and the daily burnt offering, and his meat offering, and their drink offerings, according unto their manner, for a sweet savour, a sacrifice made by fire unto the LORD.

Of the month - Belonging to every new moon.

⁷And ye shall have on the tenth day of this seventh month an holy convocation; and ye shall afflict your souls: ye shall not do any work therein:

Afflict your souls - Yourselves, by fasting and abstinence from all delightful things, and by compunction for your sins, and the judgments of God, either deserved by you or inflicted upon you.

¹²And on the fifteenth day of the seventh month ye shall have an holy convocation; ye shall do no servile work, and ye shall keep a feast unto the LORD seven days:

Seven days - Not by abstaining so long from all servile work, but by offering extraordinary sacrifices each day. This was the Feast of Tabernacles. And all the days of their dwelling in booths, they must offer sacrifices. While we are in these tabernacles, ’tis our interest as well as duty, to keep up our communion with God. Nor will the unsettledness of our outward condition, excuse our neglect of God’s worship.
