CHAPTER 29

Nu 29:1-40. The Offering at the Feast of Trumpets.

1. in the seventh month-of the ecclesiastical year, but the first month of the civil year, corresponding to our September. It was, in fact, the New Year's Day, which had been celebrated among the Hebrews and other contemporary nations with great festivity and joy and ushered in by a flourish of trumpets. This ordinance was designed to give a religious character to the occasion by associating it with some solemn observances. (Compare Ex 12:2; Le 23:24).

it is a day of blowing the trumpets unto you-This made it a solemn preparation for the sacred feasts-a greater number of which were held during this month than at any other season of the year. Although the institution of this feast was described before, there is more particularity here as to what the burnt offering should consist of; and, in addition to it, a sin offering is prescribed. The special offerings, appointed for certain days, were not to interfere with the offerings usually requisite on these days, for in Nu 29:6 it is said that the daily offerings, as well as those for the first day of the month, were to take place in their ordinary course.

Matthew Henry's Concise Commentary

29:1-11 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.
