The Day of Atonement is the next holy convocation (Leviticus 23:26-32). Observed by fasting (verse 27, compare Acts 27:9), refraining from eating or drinking (Esther 4:16), this day represents humanity's need to be reconciled to God through the forgiveness of sin.

At the return of Christ, Satan will be bound (Revelation 20:1-3) so the nations can be reconciled to the Father through Christ. Luke referred to this observance as "the fast" in Acts 27:9.
