Leviticus 23:34-36

DouayRheims(i) 34 Say to the children of Israel: From the fifteenth day of this same seventh month, shall be kept the feast of tabernacles, seven days to the Lord. 35 The first day shall be called most solemn and most holy: you shall do no servile work therein. And seven days you shall offer holocausts to the Lord. 36 The eighth day also shall be most solemn and most holy: and you shall offer holocausts to the Lord. For it is the day of assembly and congregation. You shall do no servile work therein.
