Lev 16:6 “Aaron will offer the bull as a mistake offering for himself and will provide reconciliation for himself and for his house.
Lev 16:7 Then he will take the two goats and set them in Yahveh’s sight at the entrance of the conference tent.
Lev 16:8 And Aaron will cast lots over the two goats, one lot for Yahveh and the other lot for entire removal.
Lev 16:9 And Aaron will present the goat on which the lot fell for Yahveh and use it as a mistake offering,
Lev 16:10 but the goat on which the lot fell for entire removal will be presented alive in Yahveh’s sight to provide reconciliation upon it, that it may be sent away into the wilderness for entire removal.
One of the reasons that the original name for this ceremony was the day of reconciliations (plural) is explained here. There are two goats presented, and lots are cast to see which would be sacrificed to appease Yahveh’s judgement against the nation’s sins, and which would be set free to signify forgiveness and deliverance from those sins.
Global reconciliation will also happen in two stages. The one holy sacrifice was crucified on a cross for the sins of all, to reconcile God to humanity. That part has already been done. The next stage is yet to be accomplished. When all humanity has been set free from the power and presence of sin, that is when the promise signified by the Day of Reconciliations will find its ultimate fulfilment.
LORD, thank you for the blood of Christ, shed for our reconciliation. Come, Lord Jesus, and set us free from sin forever.
