Hesabu 29:1

“ ‘Katika siku ya kwanza ya mwezi wa saba mtakuwa na kusanyiko takatifu na msifanye kazi ya kawaida. Ni siku kwa ajili yenu ya kupiga tarumbeta.

And in the seventh month, on the first day of the month, ye shall have an holy convocation; ye shall do no servile work: it is a day of blowing the trumpets unto you.
