Let there be a holy meeting. And give to the Lord a burned offering for a sweet smell.

Coming together for a holy meeting.

In the seventh month, on the first day of the month, let there be a holy meeting; on it you may do no field-work; let the day be marked by the blowing of horns;
Numbers 29:1
And give to the Lord a burned offering for a sweet smell; one ox, one male sheep, seven he-lambs of the first year, without any mark on them:
Numbers 29:2

Num 29:39 These are the offerings which you are to give to the Lord at your regular feasts, in addition to the offerings for an oath, and the free offerings you give, for your burned offerings and your drink offerings and your peace-offerings.
