Many of our Jewish people believe that the New Covenant is only for the Gentiles, and the writings of the New Testament are only for Christians, not Jews. However, in the Old Testament (Hebrew Bible) God clearly said He would establish a New Covenant with the Jewish people.

"Behold, the days are coming, says 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 that I took them by the hand to lead them out of the land of Egypt, My covenant which they broke, though I was a husband to them, says the Lord. But this is the covenant that I will make with the house of Israel after those days, says the Lord: I will put My law in their minds, and write it on their hearts; and I will be their God, and they shall be My people. No more shall every man teach his neighbor, and every man his brother, saying, 'Know the Lord,' for they all shall know Me, from the least of them to the greatest of them, says the Lord. For I will forgive their iniquity, and their sin I will remember no more." (Jer. 31:31-34)

This New Covenant was instituted by the Messiah Himself, shortly before His crucifixion, when at the Passover table He took the cup and said, "drink from it, all of you - this is the blood of the covenant which is poured out for many, for the forgiveness of sins" (Matt. 26:27-28). That cup represented the blood atonement He would make for the sins of all mankind.
