Jeremiah 31:33-34

But this is 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 in their heart will I write it; and I will be their God, and they shall be my people: 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 their sin will I remember no more.
