Leviticus 23:26-29 World English Bible (WEB)

26. Yahweh spoke to Moses, saying,

27. “However on the tenth day of this seventh month is the day of atonement: it shall be a holy convocation to you, and you shall afflict yourselves; and you shall offer an offering made by fire to Yahweh.

28. You shall do no kind of work in that same day; for it is a day of atonement, to make atonement for you before Yahweh your God.

29. For whoever it is who shall not deny himself in that same day; shall be cut off from his people.
