'Denial' in the Bible

“This is to be a permanent statute for you: In the seventh month, on the tenth day of the month you are to practice self-denial and do no work, both the native and the foreigner who resides among you.

It is a Sabbath of complete rest for you, and you must practice self-denial; it is a permanent statute.

“The tenth day of this seventh month is the Day of Atonement. You are to hold a sacred assembly and practice self-denial; you are to present a fire offering to the Lord.

If any person does not practice self-denial on this particular day, he must be cut off from his people.

It will be a Sabbath of complete rest for you, and you must practice self-denial. You are to observe your Sabbath from the evening of the ninth day of the month until the following evening.”
