Jeremiah 31:31-34

Behold, the days come, saith the LORD, that 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 bring them out of the land of Egypt; which my covenant they brake,
although I was an husband unto them, saith the LORD: But this shall be 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 write it in their
hearts; and 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 I will
remember their sin no more.
