Leviticus 23:32-36 Catholic Public Domain Version (CPDV)

32. It is a Sabbath of rest, and you shall afflict your souls beginning on the ninth day of the month: from evening until evening you shall celebrate your Sabbaths.

33. And the Lord spoke to Moses, saying:

34. Say to the sons of Israel: From the fifteenth day of this seventh month, there shall be the Feast of Tabernacles: seven days for the Lord.

35. The first day shall be called most honored and most holy; you shall do no servile work in it.

36. And for seven days you shall offer holocausts to the Lord. Likewise, the eighth day shall be most honored and most holy, and you shall offer holocausts to the Lord. For it is the day of assembly and gathering. You shall do no servile work in it.
