Numbers 29:5-7

American Standard Version

⁵ and one he-goat for a sin-offering, to make atonement for you; ⁶ besides the burnt-offering of the new moon, and the meal-offering thereof, and the continual burnt-offering and the meal-offering thereof, and their drink-offerings, according unto their ordinance, for a sweet savor, an offering made by fire unto Jehovah.

⁷ And on the tenth day of this seventh month ye shall have a holy convocation; and ye shall afflict your souls: ye shall do no manner of work;
