Leviticus 1 - 4

"In this way, the priest makes atonement for him on account of his sin and he's forgiven." Leviticus 4:35 THE MESSAGE

But when Christ appeared as a high priest of the good things to come, He entered through the greater and more perfect tabernacle, not made with hands, that is to say, not of this creation; and not through the blood of goats and calves, but through His own blood, He entered the holy place once for all, having obtained eternal redemption. Hebrews 9:11-12 NASB

How much more will the blood of Christ, who through the eternal Spirit offered Himself without blemish to God, cleanse your conscience from dead works to serve the living God? Hebrews 9:14 NASB
