Leviticus 23:25-28

²⁵You must do no ordinary work, and you must offer a sacrifice made by fire to Yahweh.'”

²⁶Then Yahweh spoke to Moses, saying,

²⁷“Now the tenth day of this seventh month is the Day of Atonement. It is to be a holy assembly, and you must humble yourselves and present to Yahweh an offering by fire.

²⁸You must do no work on that day because it is the Day of Atonement, to make atonement for yourselves before Yahweh your God.
