Leviticus 23:34-36

ERV(i) 34 Speak unto the children of Israel, saying, On the fifteenth day of this seventh month is the feast of tabernacles for seven days unto the LORD. 35 On the first day shall be an holy convocation: ye shall do no servile work. 36 Seven days ye shall offer an offering made by fire unto the LORD: on the eighth day shall be an holy convocation unto you; and ye shall offer an offering made by fire unto the LORD: it is a solemn assembly; ye shall do no servile work.
