Jeremiah 31:33-34

For this is the covenant that I will make with the house of Israel, after those days, saith Jehovah: I will put my law in their inward parts, and will write it in their heart; 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 Jehovah; for they shall all know me, from the least of them unto the greatest of them, saith Jehovah: for I will pardon their iniquity, and their sin will I remember no more.
