For the life of the flesh is in the blood, and I have given it for you on the altar to make atonement for your souls, for it is the blood that makes atonement by the life. - Leviticus 17:11
Lord's supper
26 Now as they were eating, Jesus took bread, and after blessing it broke it and gave it to the disciples, and said, "Take, eat; this is my body."
27 And he took a cup, and when he had given thanks he gave it to them, saying, "Drink of it, all of you,
28 for this is my blood of the covenant, which is poured out for many for the forgiveness of sins. - Matthew 26:26-28
And he said to them, "This is my blood of the covenant, which is poured out for many. - Mark 14:24
Justified by faith
25 whom God put forward as a propitiation by his blood, to be received by faith. This was to show God's righteousness, because in his divine forbearance he had passed over former sins.
26 It was to show his righteousness at the present time, so that he might be just and the justifier of the one who has faith in Jesus. - Romans 3:25-26
Since, therefore, we have now been justified by his blood, much more shall we be saved by him from the wrath of God. - Romans 5:9
Redemption
7 In him we have redemption through his blood, the forgiveness of our trespasses, according to the riches of his grace,
8 which he lavished upon us, in all wisdom and insight
9 making known to us the mystery of his will, according to his purpose, which he set forth in Christ - Ephesians 1:7-9
13 He has delivered us from the domain of darkness and transferred us to the kingdom of his beloved Son,
14 in whom we have redemption, the forgiveness of sins. - Colossians 1:13-14
Reconciliation
19 For in him all the fullness of God was pleased to dwell,
20 and through him to reconcile to himself all things, whether on earth or in heaven, making peace by the blood of his cross. - Colossians 1:19-20
Sanctified
So Jesus also suffered outside the gate in order to sanctify the people through his own blood. - Hebrews 13:12
Cleanse from Sin
7 But if we walk in the light, as he is in the light, we have fellowship with one another, and the blood of Jesus his Son cleanses us from all sin.
8 If we say we have no sin, we deceive ourselves, and the truth is not in us.
9 If we confess our sins, he is faithful and just to forgive us our sins and to cleanse us from all unrighteousness.
10 If we say we have not sinned, we make him a liar, and his word is not in us. - 1 John 1:7-10
Freedom
5 and from Jesus Christ the faithful witness, the firstborn of the dead, and the ruler of kings on earth. To him who loves us and has freed us from our sins by his blood
6 and made us a kingdom, priests to his God and Father, to him be glory and dominion forever and ever. Amen.
7 Behold, he is coming with the clouds, and every eye will see him, even those who pierced him, and all tribes of the earth will wail on account of him. Even so. Amen.
8 "I am the Alpha and the Omega," says the Lord God, "who is and who was and who is to come, the Almighty." - Revelation 1:5-8
New Eternal Covenant Through the Blood of the Great High Priest Jesus
11 But when Christ appeared as a high priest of the good things that have come, then through the greater and more perfect tent (not made with hands, that is, not of this creation)
12 he entered once for all into the holy places, not by means of the blood of goats and calves but by means of his own blood, thus securing an eternal redemption.
13 For if the blood of goats and bulls, and the sprinkling of defiled persons with the ashes of a heifer, sanctify for the purification of the flesh,
14 how much more will the blood of Christ, who through the eternal Spirit offered himself without blemish to God, purify our conscience from dead works to serve the living God.
15 Therefore he is the mediator of a new covenant, so that those who are called may receive the promised eternal inheritance, since a death has occurred that redeems them from the transgressions committed under the first covenant.
16 For where a will is involved, the death of the one who made it must be established.
17 For a will takes effect only at death, since it is not in force as long as the one who made it is alive.
18 Therefore not even the first covenant was inaugurated without blood.
19 For when every commandment of the law had been declared by Moses to all the people, he took the blood of calves and goats, with water and scarlet wool and hyssop, and sprinkled both the book itself and all the people,
20 saying, "This is the blood of the covenant that God commanded for you."
21 And in the same way he sprinkled with the blood both the tent and all the vessels used in worship.
22 Indeed, under the law almost everything is purified with blood, and without the shedding of blood there is no forgiveness of sins.
23 Thus it was necessary for the copies of the heavenly things to be purified with these rites, but the heavenly things themselves with better sacrifices than these.
24 For Christ has entered, not into holy places made with hands, which are copies of the true things, but into heaven itself, now to appear in the presence of God on our behalf.
25 Nor was it to offer himself repeatedly, as the high priest enters the holy places every year with blood not his own,
26 for then he would have had to suffer repeatedly since the foundation of the world. But as it is, he has appeared once for all at the end of the ages to put away sin by the sacrifice of himself.
27 And just as it is appointed for man to die once, and after that comes judgment,
28 so Christ, having been offered once to bear the sins of many, will appear a second time, not to deal with sin but to save those who are eagerly waiting for him. - Hebrews 9:11-28
