“In the seventh month (Tishri), in the first day of the month, shall be a solemn rest unto you, a memorial proclaimed with the blast of horns, a holy convocation.” –Leviticus 23:24, JPS Tanakh
“And it shall be a statute for ever unto you: in the seventh month (Tishri), on the tenth day of the month, ye shall afflict your souls, and shall do no manner of work, the home-born, or the stranger that sojourneth among you. For on this day shall atonement be made for you, to cleanse you; from all your sins shall ye be clean before the LORD.”—Leviticus 16:29-30, JPS Tanakh
“On the fifteenth day of this seventh month is the feast of tabernacles for seven days unto the LORD. On the first day shall be a holy convocation; ye shall do no manner of servile work. Seven days ye shall bring an offering made by fire unto the LORD; on the eighth day shall be a holy convocation unto you; and ye shall bring an offering made by fire unto the LORD; it is a day of solemn assembly; ye shall do no manner of servile work.” –Leviticus 23:34-36, JPS Tanakh
