Numbers 29:7

And on the tenth day a holy convocation On this day was offered annually their seventh national sacrifice. It was the great day of atonement, a day of special humiliation, fasting, and prayer; concerning the particular ceremonies whereof, see on Leviticus 16:29; and Leviticus 23:27. Afflict your souls Yourselves, by abstinence from all delightful things, and by compunction for your sins, and the judgments of God, either deserved by you, or inflicted upon you.
