Leviticus 23:28

28 and you shall do no work during that entire day; for it is a day of atonement, to make atonement on your behalf before the Lord your God.

Leviticus 23:28 In-Context

26 The Lord spoke to Moses, saying:
27 Now, the tenth day of this seventh month is the day of atonement; it shall be a holy convocation for you: you shall deny yourselves and present the Lord's offering by fire;
28 and you shall do no work during that entire day; for it is a day of atonement, to make atonement on your behalf before the Lord your God.
29 For anyone who does not practice self-denial during that entire day shall be cut off from the people.
30 And anyone who does any work during that entire day, such a one I will destroy from the midst of the people.
