"And he took the cup, and gave thanks, and gave [it] to them, saying, Drink ye all of it; For this is my blood of the new testament, which is shed for many for the remission of sins."
- Matthew 26:27-28

"But now hath he obtained a more excellent ministry, by how much also he is the mediator of a better covenant, which was established upon better promises.
For if that first [covenant] had been faultless, then should no place have been sought for the second.
For finding fault with them, he saith, Behold, the days come, saith the Lord, when I will make a new covenant with the house of Israel and with the house of Judah:
Not according to the covenant that I made with their fathers in the day when I took them by the hand to lead them out of the land of Egypt; because they continued not in my covenant, and I regarded them not, saith the Lord.
For this [is] the covenant that I will make with the house of Israel after those days, saith the Lord; I will put my laws into their mind, and write them in their hearts: and I will be to them a God, and they shall be to me a people:
And they shall not teach every man his neighbour, and every man his brother, saying, Know the Lord: for all shall know me, from the least to the greatest.
For I will be merciful to their unrighteousness, and their sins and their iniquities will I remember no more.
In that he saith, A new [covenant], he hath made the first old. Now that which decayeth and waxeth old [is] ready to vanish away. " - Hebrews 8:6-13
