Leviticus 23:35

32 Let this be a Sabbath of special rest to you, and keep yourselves from all pleasure; on the ninth day of the month at nightfall from evening to evening, let this Sabbath be kept.

33 And the Lord said to Moses,

34 Say to the children of Israel, On the fifteenth day of this seventh month let the feast of tents be kept to the Lord for seven days.

35 On the first day there will be a holy meeting: do no field-work.

36 Every day for seven days give an offering made by fire to the Lord; and on the eighth day there is to be a holy meeting, when you are to give an offering made by fire to the Lord; this is a special holy day: you may do no field-work on that day.

37 These are the fixed feasts of the Lord, to be kept by you as holy days of worship, for making an offering by fire to the Lord; a burned offering, a meal offering, an offering of beasts, and drink offerings; every one on its special day;

38 In addition to the Sabbaths of the Lord, and in addition to the things you give and the oaths you make and the free offerings to the Lord.
