Hebrews 9:19-22

9:19 For when Moses had spoken every command to all the people according to the law, 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, 9:20 and said, “This is the blood of the covenant that God has commanded you to keep.” ¹  9:21 And both the tabernacle and all the utensils of worship he likewise sprinkled with blood. 9:22 Indeed according to the law almost everything was purified with blood, and without the shedding of blood there is no forgiveness.

Hebrews 11:28

11:28 By faith he kept the Passover and the sprinkling of the blood, ²  so that the one who destroyed the firstborn would not touch them.

Hebrews 12:24

12:24 and to Jesus, the mediator ³  of a new covenant, and to the sprinkled blood that speaks of something better than Abel’s does. ⁴ 

[9:20]  ¹ tn Grk “which God commanded for you (or in your case).”

[11:28]  ² tn Grk “the pouring out of the blood.”

[12:24]  ³ tn The Greek word μεσίτης (mesith", “mediator”) in this context does not imply that Jesus was a mediator in the contemporary sense of the word, i.e., he worked for compromise between opposing parties. Here the term describes his function as the one who was used by God to enact a new covenant which established a new relationship between God and his people, but entirely on God’s terms.

[12:24]  ⁴ sn Abel’s shed blood cried out to the Lord for justice and judgment, but Jesus’ blood speaks of redemption and forgiveness, something better than Abel’s does (Gen 4:10; Heb 9:11-14; 11:4).
