Leviticus 23:27

²⁹“It shall be a statute to you forever: in the seventh month, on the tenth day of the month, you shall afflict your souls, and shall do no kind of work, whether native-born or a stranger who lives as a foreigner among you; ³⁰for on this day shall atonement be made for you, to cleanse you. You shall be clean from all your sins before the LORD. ³¹It is a Sabbath of solemn rest to you, and you shall afflict your souls. It is a statute forever.

²⁴Then he shall bathe himself in water in a holy place, put on his garments, and come out and offer his burnt offering and the burnt offering of the people, and make atonement for himself and for the people.

¹⁰Aaron shall make atonement on its horns once in the year; with the blood of the sin offering of atonement once in the year he shall make atonement for it throughout your generations. It is most holy to the LORD.”

¹⁵“Then he shall kill the goat of the sin offering that is for the people, and bring his blood within the veil, and do with his blood as he did with the blood of the bull, and sprinkle it on the mercy seat and before the mercy seat.

⁵Is this the fast that I have chosen? A day for a man to humble his soul? Is it to bow down his head like a reed, and to spread sackcloth and ashes under himself? Will you call this a fast, and an acceptable day to the LORD?

⁷“‘On the tenth day of this seventh month you shall have a holy convocation. You shall afflict your souls. You shall do no kind of work; ⁸but you shall offer a burnt offering to the LORD for a pleasant aroma: one young bull, one ram, seven male lambs a year old, all without defect; ⁹and their meal offering, fine flour mixed with oil: three tenths for the bull, two tenths for the one ram, ¹⁰one tenth for every lamb of the seven lambs; ¹¹one male goat for a sin offering, in addition to the sin offering of atonement, and the continual burnt offering, and its meal offering, and their drink offerings.

¹⁰For godly sorrow produces repentance leading to salvation, which brings no regret. But the sorrow of the world produces death. ¹¹For behold, this same thing, that you were grieved in a godly way, what earnest care it worked in you. Yes, what defense, indignation, fear, longing, zeal, and vindication! In everything you demonstrated yourselves to be pure in the matter.

¹⁰I will pour on David’s house and on the inhabitants of Jerusalem the spirit of grace and of supplication. They will look to me^[+] they have pierced; and they shall mourn for him as one mourns for his only son, and will grieve bitterly for him as one grieves for his firstborn.

¹¹“Aaron shall present the bull of the sin offering, which is for himself, and shall make atonement for himself and for his house, and shall kill the bull of the sin offering which is for himself.

²In those days I, Daniel, was mourning three whole weeks. ³I ate no pleasant food. No meat or wine came into my mouth. I didn’t anoint myself at all, until three whole weeks were fulfilled.
