Hebrews 7:22

Another Priest, Like Melchizedek

²¹ (for [Levitical] priests were appointed without [God] taking [such] an oath, but Christ was appointed with an oath by God when He said to Him [Psa. 110:4], "The Lord made a vow and will not change His mind [when He said], 'You are a priest forever')." ²² So therefore, Jesus has become the guarantee of a better Agreement [between God and mankind]. ²³ And on one hand, many people were appointed to be [Levitical] priests because they were prevented by death from continuing [to serve]. [Note: The idea is that Levitical priests had to be constantly replaced].

Better Covenant

Jesus

Matthew 26:28

for this is [i.e., represents] my blood of the Agreement [i.e., between God and mankind], which is [to be] poured out for many people in order for [their] sins to be forgiven.

Mark 14:24

And He said to them, "This is [i.e., represents] my blood of the Agreement [i.e., between God and mankind] which is [to be] poured out for many people.

Luke 22:20

And in the same way He took [another] cup, after the [Passover] meal, and said, "This cup is [i.e., represents] the New Agreement [i.e., between God and mankind] made by my blood, which is [to be] poured out for you.

1 Corinthians 11:25

In the same way [He took] the cup also, after supper, and said, "This cup [i.e., its contents] represents the New Agreement [ratified] by my blood. [Continue to] do this, whenever you people drink from it, in memory of me."

Hebrews 8:6-12

But now Jesus has obtained a ministry that is as far superior [to that of the Levitical priesthood] as the [New] Agreement, of which He is the Mediator, is better [than the old one], because it has been enacted on better promises.

Hebrews 9:15-23

Therefore, Christ is the Mediator of a New Agreement, so that [all] those people who have been called [by God] can receive the promise of the never ending inheritance. [This is possible because] a death has taken place for the redemption of [people's] sins who lived under the first Agreement.

Hebrews 12:24

and to Jesus, the Mediator of a New Agreement [between God and mankind], and to the sprinkled blood [of Jesus], which says better things [to us] than [the blood of] Abel did. [Note: The contrast seems to be that "Abel's blood called for vengeance and death (See Gen. 4:10) whereas the blood of Christ provides mercy and life"].

Hebrews 13:20

Now may the God of peace, who brought back from the dead our Lord Jesus, the great Shepherd of the sheep [i.e., the church], through the blood of the never ending Agreement [i.e., Christ's blood],
