Speak unto the children of Israel, saying, In the {k} seventh month, in the first day of the month, shall ye {l} have a sabbath, a memorial of {m} blowing of trumpets, an holy convocation.

(k) That is, about the end of September.

(l) Or, a holy day to the Lord.

(m) Which blowing was to remind them of the many feasts that were in that month, and of the Jubile.

Wesley's Notes

23:24 A sabbath - Solemnized with the blowing of trumpets by the priests, not in a common way, as they did every first day of every month, but in an extraordinary manner, not only in Jerusalem, but in all the cities of Israel. They began to blow at sun - rise, and continued blowing till sun - set. This seems to have been instituted, To solemnize the beginning of the new year, whereof as to civil matters and particularly as to the Jubilee, this was the first day; concerning which it was fit the people should be admonished, both to excite their thankfulness for God's blessings in the last year, and to direct them in the management of their civil affairs. To put a special honour upon this month. For as the seventh day was the sabbath, and the seventh year was a sabbatical year, so God would have the seventh month to be a kind of sabbatical month, for the many sabbaths and solemn feasts which were observed in this more than in any other month. And by this sounding of the trumpets in its beginning, God would quicken and prepare them for the following sabbaths, as well as that of atonement and humiliation for their sins, as those of thanksgiving for God's mercies.

Scofield Reference Notes

[2] trumpets

The feast of Trumpets, Lev 23:23-25. This feast is a prophetical type and refers to the future regathering of long-dispersed Israel. A long interval elapses between Pentecost and Trumpets, answering to the long period occupied in the pentecostal work of the Holy Spirit in the present dispensation. Study carefully Isa 18:3 27:13 (with contexts); Isa 58:1-14 (entire chapter), and Joel 2:1-3:21 in connection with the "trumpets," and it will be seen that these trumpets, always symbols of testimony, are connected with the regathering and repentance of Israel after the church, or pentecostal period is ended. This feast is immediately followed by the day of atonement.

Margin seventh month

i.e. October; also Lev 23:27,34,39,41.

Jamieson-Fausset-Brown Bible Commentary

24. In the seventh month, in the first day of the month, shall ye have a sabbath-That was the first day of the ancient civil year.

a memorial of blowing of trumpets-Jewish writers say that the trumpets were sounded thirty successive times, and the reason for the institution was for the double purpose of announcing the commencement of the new year, which was (Le 23:25) to be religiously observed (see Nu 29:3), and of preparing the people for the approaching solemn feast.

Matthew Henry's Concise Commentary

23:23-32 the blowing of trumpets represented the preaching of the gospel, by which men are called to repent of sin, and to accept the salvation of Christ, which was signified by the day of atonement. Also it invited to rejoice in God, and become strangers and pilgrims on earth, which was denoted by the feast of Tabernacles, observed in the same month. At the beginning of the year, they were called by this sound of trumpet to shake off spiritual drowsiness, to search and try their ways, and to amend them. The day of atonement was the ninth day after this; thus they were awakened to prepare for that day, by sincere and serious repentance, that it might indeed be to them a day of atonement. The humbling of our souls for sin, and the making our peace with God, is work that requires the whole man, and the closest application of mind. On that day God spake peace to his people, and to his saints; therefore they must lay aside all their wordly business, that they might the more clearly hear that voice of joy and gladness.
