Jeremiah 31:31-34
31, Behold, the days come, said 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 broke, although I was an husband to them, said the LORD:
33, But this shall be the covenant that I will make with the house of Israel; After those days, said 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 neighbor, and every man his brother, saying, Know the LORD: for they shall all know me, from the least of them to the greatest of them, said the LORD: for I will forgive their iniquity, and I will remember their sin no more.
