| Barnes' Notes on the Bible The offering on the great Day of Atonement was the same with that just specified. The great ceremonies of the day are described in Leviticus 16.
Clarke's Commentary on the BibleOn the tenth day - See the notes on Leviticus 16:29, and Leviticus 23:24 (note).
Gill's Exposition of the Entire BibleAnd ye shall have on the tenth day of the seventh month an holy convocation,.... The month Tisri, as before; so the Targum of Jonathan: and ye shall afflict your souls; or persons; their bodies by fasting, and their souls by repentance and humiliation; for this was a grand fast, as it is called Acts 27:9, ye shall not do any work therein; see Leviticus 23:28.
Keil and Delitzsch Biblical Commentary on the Old TestamentOn the day of atonement, on the tenth of the seventh month, a similar festal sacrifice was to be offered to the one presented on the seventh new moon's day (a burnt-offering and sin-offering), in addition to the sin-offering of atonement prescribed at Leviticus 16, and the daily burnt-offerings. For a more minute description of this festival, see at Leviticus 16 and Leviticus 23:26-32.
Geneva Study BibleAnd ye shall have on the tenth day of this seventh month an holy {d} convocation; and ye shall afflict your souls: ye shall not do any work therein: (d) Which is the feast of reconciliation.
Wesley's Notes 29:7 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.
Jamieson-Fausset-Brown Bible Commentary7-11. ye shall have on the tenth day of this seventh month an holy convocation-This was the great day of atonement. Its institution, together with the observance to which that day was devoted, was described (Le 16:29, 30). But additional offerings seem to be noticed, namely, the large animal sacrifice for a general expiation, which was a sweet savor unto the Lord, and the sin offering to atone for the sins that mingled with that day's services. The prescriptions in this passage appear supplementary to the former statement in Leviticus.
Matthew Henry's Concise Commentary29:1-11 There were more sacred solemnities in the seventh month than in any other. It was the space between harvest and seed-time. The more leisure we have from the pressing occupations of this life, the more time we should spend in the immediate service of God. The blowing of the trumpets was appointed, Le 22:24. Here they are directed what sacrifices to offer on that day. Those who would know the mind of God in the Scriptures, must compare one part with another. The latter discoveries of Divine light explain what was dark, and supply what was wanting, in the former, that the man of God may be perfect. |
