7 Bible Verses about Revelation, In Ot

And He took a cup [i.e., probably wine made from fresh or possibly preserved grape juice], gave thanks to God, then passed it to them, saying, "All of you, drink from it; 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.

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.

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.

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."

For God found fault with the Israelites [or, possibly with the first Agreement], saying [Jer. 31:31ff], "Look, the Lord says, the time will come when I will make a New Agreement with the people of Israel and with the people of Judah. [It will] not be like the Agreement that I made with their forefathers on the day I took them by the hand to lead them out of the country of Egypt. For they did not [continue to] keep my Agreement, so I did not regard them [as acceptable], says the Lord. For this is the Agreement that I will make with the people of Israel in the coming days, says the Lord: I will put my laws into their minds, and I will also write them on their hearts. And I will be their God and they will be my people.read more.
And everyone will not [have to] teach his neighbor or his brother [anymore], telling them to 'Know the Lord,' because all of them will know me [as their Lord], from the least [important] ones to the most important ones. For I will be merciful to their wickedness [i.e., by forgiving them] and I will not remember their sins anymore."

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.

And the Holy Spirit also testifies to us, for He said, first of all, [Jer. 31:33f], "The Lord says, this is the Agreement I will make with them [i.e., with my people] after those days. I will put my laws in their hearts and I will write them on their minds." Then He said, "And I will not remember their sins or their wickedness anymore."read more.
Now where forgiveness of sins has taken place, there is no longer [a need for an] offering for sin.
