Numbers 29:1
Amplified Bible (AMP)
ON THE first day of the seventh month [on New Year''s Day of the civil year], you shall have a holy [summoned] assembly; you shall do no servile work. It is a day of blowing of trumpets for you [everyone blowing who wishes, proclaiming that the glad New Year has come and that the great Day of Atonement and the Feast of Tabernacles are now approaching].— Numbers 29:1 (AMP)
