Leviticus 23:34-36

King James Version

³⁴ Speak unto the children of Israel, saying, The fifteenth day of this seventh month shall be 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 therein.

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; and ye shall do no servile work therein.
