Jeremiah 31
33 Ref But this is the agreement which I will make with the people of Israel after those days, says the Lord; I will put my law in their inner parts, writing it in their hearts; and I will be their God, and they will be my people.
34 Ref And no longer will they be teaching every man his neighbour and every man his brother, saying, Get knowledge of the Lord: for they will all have knowledge of me, from the least of them to the greatest of them, says the Lord: for they will have my forgiveness for their evil-doing, and their sin will go from my memory for ever.
