Leviticus 23:24 - Clarke's commentary and critical notes on the Bible

Speak unto the children of Israel, saying, In the seventh month, in the first day of the month, shall ye have a sabbath, a memorial of blowing of trumpets, an holy convocation. A memorial of blowing of trumpets - This is generally called the feast of trumpets; and as it took place on the first day of the seventh month, Tisri, which answers to September, which month was the commencement of what was called the civil year, the feast probably had no other design than to celebrate the commencement of that year, if indeed such a distinction obtained among the ancient Jews. See the note on Exodus 12:2. Some think creation began at this time.
