I'm still debating if we are in the new covenant/testament or not. Compare this to Matthew 26:28 above

Jeremiah 31:31. Behold, the days come, saith the Lord, that I will make a new covenant with the house of Israel, and with the house of Judah:32. Not according to the covenant that I made with their fathers in the day that I took them by the hand to bring them out of the land of Egypt; which my covenant they brake, although I was an husband unto them, saith the Lord:33. But this shall be the covenant that I will make with the house of Israel; After those days, saith the Lord, I will put my law in their inward parts, and write it in their hearts; and will be their God, and they shall be my people.34. And they shall teach no more every man his neighbour, and every man his brother, saying, Know the Lord: for they shall all know me, from the least of them unto the greatest of them, saith the Lord: for I will forgive their iniquity, and I will remember their sin no more.
