TSK · Leviticus 16:21

He must lay his hand on the head of the burnt offering, and it will be accepted for him to make atonement on his behalf.

However, when they confess their iniquity and their ancestors’ iniquity which they committed by trespassing against me, by which they also walked in hostility against me

may your ear be attentive and your eyes be open to hear the prayer of your servant that I am praying to you today throughout both day and night on behalf of your servants the Israelites. I am confessing the sins of the Israelites that we have committed against you– both I myself and my family have sinned.

Then I confessed my sin; I no longer covered up my wrongdoing. I said,“I will confess my rebellious acts to the LORD.” And then you forgave my sins.(Selah)

The one who covers his transgressions will not prosper, but whoever confesses them and forsakes them will find mercy.

So I turned my attention to the Lord God to implore him by prayer and requests, with fasting, sackcloth, and ashes.

God made the one who did not know sin to be sin for us, so that in him we would become the righteousness of God.
