John Wesley on Numbers 29

Of the month - Belonging to every new moon.

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.

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.
